Need to decide whether the given information in the statements (taken singly or together) is sufficient to answer the question.6) How many students passed the exam if 20 students failed in the exam?I.Thousand students were issued hall tickets for the exam.II. 10% of the students who appeared for the exam failed.a) If the question cannot be answered even with the help of both the statements together.b) If the question can be answered with the help of statement II alone.c) If the question can be answered with the help of statement I alone.d) If the question can be answered with the help of both statements together.Ans: bExplanation:Information given in the question has to be noted first. The number of students who failed is given as 20. The statement I alone is not sufficient since the number of students who appeared is not known.Using statement II alone, if 10% of the students appeared have failed, then 90% of students appeared have passed. It is given in the question that 20 students have failed. 10% of appeared =20, 90% of appeared can be found.7) What is the value of X?I. X4= 2401II.X2+ 3X - 24 = 0.5(6X + 50)a) If the question cannot be answered even with the help of both the statements together.b) If the question can be answered with the help of statement II alone.c) If the question can be answered with the help of statement I alone.d) If the question can be answered with the help of both statements together.Ans: aExplanation:From statement I, we obtain X = +7 or -7. As we cannot uniquely determine the value of X, statements I alone Is not sufficient to answer the question.From statement II, we obtain X =+7 or -7. As we cannot uniquely determine the value of X. So, even the two statements together are not sufficient to answer the question.Hence the answer is a.8) If a salesman received a commission of 3% of the sales that he has booked in a month, what was the sale booked by the salesman in the month of November 2003?I. The sales booked by the salesman in the month of November 2003 minus salesman's commission was $245,000II. The selling price of the sales booked by the salesman in the month of November 2003 was 125 percent of the original purchase price of $225,000a) If the question can be answered with the either of the statement alone.b) If the question can be answered with the help of statement II alone.c) If the question can be answered with the help of statement I alone.d) If the question can be answered with the help of both statements together.Ans: aExplanation:From statement 1, we know the sales value after the salesman's commission is subtracted.From the question stem, we know his commission is 3% of the sales booked. Then the value of sales after subtracting his commission is 100 - 3 = 97% of the sales booked. Putting the two together, we can deduce that 97% of sales booked = $245,000. So we can find out the sales booked.9) Is the positive integer m divisible by 6?I. m is divisible by 3II. m is divisible by 4a) If the question cannot be answered even with the help of both the statements together.b) If the question can be answered with the help of statement II alone.c) If the question can be answered with the help of statement I alone.d) If the question can be answered with the help of both statements together.Ans: dExplanation:From statement 2, if m is divisible by 4, it will definitely be divisible by 2.So, by combining the two statements, we know that m is divisible by 3 and by 2. Hence, we can conclude that m is divisible by 6.10) What is the distance between Chandigarh and Delhi?I. Karnal is 130 km from Chandigarh.II. Delhi is 120 km from Karnal.a) If the question cannot be answered even with the help of both the statements together.b) If the question can be answered with the help of statement II alone.c) If the question can be answered with the help of statement I alone.d) If the question can be answered with the help of both statements together.Ans: aExplanation:Chandigarh, Karnal, and Delhi are in a straight line and Karnal lies between Chandigarh and Delhi.Even if it is given that these 3 cities are in straight line, still we have 2 possible answers to this question, even after combining the two statements i.e 250 km and 10 km.Since we are not getting any unique answer even after combining the two statements.Data Arrangements 11-12:11) In a college there are seven clubs: Drama, Astronomy, Music, Dance, Cookery, Debate and Science. Each of these clubs meets on a Different day of the week, one on each day beginning Sunday. The Drama club must meet on a Sunday.

Therefore remaining inner small cubes will be the cubes having two sides green colored. So the required number = 24 - 16 = 8Cubes 21-23:Each of the six faces of a cube is painted in exactly one of the four colors, A, B, C and D, where A, B, C, D corresponds to different colors such that each face is at least one face that is painted in each color. The cube is then placed on a table and cut into 60 identical small cuboids by making the least possible number of cuts, each cut being parallel to some face of the cube.21) What is the least possible number of small cuboids which have no face painted A?a) 15b) 20c) 24d) 40Ans: aExplanation:The given cube is cut into 60 identical cuboids with least number of cuts. This can be done when the dimensions of the cube are 3 x 4 x 5. Hence the number of cuts is 2 + 3 + 4 = 9.Now, we also need to select which 3 sides to paint with A, as the number of cuboids on each side are different. Naturally, we need to choose the three sides with the largest number of cuboids. This can be found on the two 5 x 4 faces and the 5 x 3 face. Also, these three faces are adjacent to each other. The two 5 x 4 faces will each contain 20 cuboids, a total of 40 cuboids. These faces lie exactly opposite each other.The 5 x 3 face will be between these two faces. This face has 15 cuboids out of which 10 are already accounted for. Hence this side gives 5 more cuboids painted in white. The total number of cuboids painted in white is hence 45. Therefore, a total of 15 (60 - 45) cuboids are not painted in white and this is the lowest such number.22) What is the maximum possible number of small cuboids which have more than one face painted in the same color?a) 9b) 10c) 12d) 14Ans: bExplanation:In the figure, the green colored highlighted area contains cuboids which have the same color lets say A. The other faces before it was cut are B, C, and D each with other different colors.23) What is the maximum possible number of small cuboids which have all the sides painted?a) 10b) 8c) 0d) 6Ans: cExplanation:No cuboid can have all the faces painted.Cubes 24-27:There are 128 cubes with me which are colored according to two schemes viz.64 cubes each having two red adjacent faces and one yellow and other blue on their opposite faces while green on the rest.64 cubes each having two adjacent blue faces and one red and other green on their opposite faces, while red on the rest. They are then mixed up.24) How many cubes have at least two colored red faces each?a) 0b) 32c) 64d) 128Ans: dExplanation:64 and 64 cubes of both types of cubes are such who have at least two colored faces red each. Therefore, the total number of the required cubes is 128.25) What is the total number of red faces?a) 0b) 64c) 320d) 128Ans: cExplanation:No. of red faces among first 64 cubes =64*2=128No. of red faces among second 64 cubes =64*3= 192Therefore, total number of red faces = 128 + 192 = 32026) How many cubes have only one red face each?a) 128b) 32c) 0d) NoneAns: aExplanation:Out of 128 cubes, no cube has only one face as red.27) Which two colour shave the same number of faces?a) Red and Yellowb) Blue and Greenc) Red and Greend) Red and BlueAns: bExplanation:First 64 cubes are such each of whose two faces are green and second 64 cubes are such each of whose two faces are blue. Therefore, green and blue colors have the same number of faces.28) In a survey of university students, 64 had taken the mathematics course, 94 had taken the chemistry course, 58 had taken the physics course, 28 had taken mathematics and physics, 26 had taken mathematics and chemistry, 22 had taken chemistry and physics course, and 14 had taken all the three courses.

Till quite recently Nature had her own sanctuaries, where man either did not go at all or only as a tool-using animal in comparatively small numbers. But now, in this machinery age, there is no place left where man cannot go with overwhelming forces at his command. He can strangle to death all the nobler wildlife in the world today. To-morrow he certainly will have done so, unless he exercises due foresight and self-control in the meantime.There is not the slightest doubt that birds and mammals are now being killed off much faster than they can breed. And it is always the largest and noblest forms of life that suffer the most. The whales and elephants, lions and eagles, go. The rats and flies and all mean parasites remain. This is inevitable in certain cases. But it is wanton killing off that I am speaking of to-night.Civilized man begins by destroying the very forms of wildlife he learns to appreciate most when he becomes still more civilized. The obvious remedy is to begin conservation at an earlier stage, when it is easier and better in every way, by enforcing laws for close seasons, game preserves, the selective protection of certain species, and sanctuaries.I have just defined a sanctuary as a place where man is passive and the rest of Nature active. But this general definition is too absolute for any special case. The mere fact that man has to protect a sanctuary does away with his purely passive attitude. Then, he can be beneficially active by destroying pests and parasites, like bot-flies or mosquitoes, and by finding antidotes for diseases like the epidemic which periodically kills off the rabbits and thus starves many of the carnivora to death. But, except in cases where the experiment has proved his intervention to be beneficial, the less he upsets the balance of Nature the better, even when he tries to be an earthly Providence.11) The author implies that his first definition of a sanctuary is:A) Totally wrongB) Somewhat idealisticC) unhelpfulD) indefensibleE) immutableYour Answer Options:1) A2) B3) C4) D5) EAns: Option 2Explanation:The author says in sentence two that his previous definition was too absolute. Yet he admits that the less man upsets the balance of Nature the better. Hence his definition is not entirely right (because it is too idealistic) but it is not entirely wrong either. It is now easy to eliminate answers A, C, D, and E because they are strongly negative.12) The authors argument that destroying bot-flies and mosquitoes would be a beneficial action is most weakened by all of the following exceptA) parasites have an important role to play in the regulation of populationsB) the elimination of any species can have unpredictable effects on the balance of natureC) the pests themselves are part of the food chainD) these insects have been introduced to the area by human activitiesE) elimination of these insects would require the use of insecticides that kill a wide range of insectsYour Answer Options:1) B2) C & D3) A4) D5) EAns: Option 4Explanation:In except questions find the true statements first. In this case, find four statements that weaken the idea that destroying pests is beneficial. That means finding statements that show that it is not a good idea to destroy the pests. Answers A, B, C, and E give reasons why destroying these insects might be a mistake. D, however, is the right answer because it suggests that eliminating these insects might not be wrong since they are not even natural inhabitants of the area.13) It can be inferred that the passage is:a) part of an article in a scientific journalb) extracted from the minutes of a nature clubc) part of a speech delivered to an educated audienced) a speech delivered in a court of lawe) from a polemical article published in a magazineYour Answer Options:1) D & E2) A3) C4) B5) DAns: Option 3Explanation:From the words I am speaking of tonight we can infer that the words were delivered orally, and not during theday time. The only possible answer is C.14) What should be the most appropriate central idea of this passage:A) The author argues that man kills big animals but saves mosquitoes & other parasites.B) Man is selfish by nature so he is up against the wildlife which is harmful for his survivalC) Ecological balance, if not maintained by man will be harmful in long run.D) Author proposes a programme for not disturbing the balance of nature as it is beneficial for mankind.E) In view of the author,man should not intervene in natural environments.Your Answer Options1) A2) D3) C4) E5) BAns: Option 3Explanation:The author in his last paragraph warns the man against his attitude and suggests not to create disturbance in the ecological system and should have foresight for his own benefit.15)Tone of the Author as expressed in the passage can be best describedA) Descriptive to analyticalB) Sarcastically humorousC) Objective to narrativeD) Sarcastically critical to suggestiveE) Ironically sarcastic to negativeYour Answer Options1) A2) C3) D4) E5) BAns: Option 3Explanation:Very first paragraph determines the tone which goes on to criticise the human activities against nature sarcastically yet issues a suggestive warning to exercise due foresight and self-control. Entire passage revolves around this tone and concludes with the suggestion not to disturb the ecological balance.Directions for questions 16 to 20 - Read the short passage below and answer the questions that follow:Marie was born in 1867 in Warsaw, Poland, where her father was a Professor of Physics. At an early age, she displayed a brilliant mind and a blithe personality. Her great exuberance for learning prompted her to continue with her studies after high school. She became disgruntled, however, when she learned that the university in Warsaw was closed to women. Determined to receive a higher education, she defiantly left Poland and in 1891 entered the Sorbonne, a French university, where she earned her master's degree and doctorate in physics.Marie was fortunate to have studied at the Sorbonne with some of the greatest scientists of her day, one of whom was Pierre Curie. Marie and Pierre were married in 1895 and spent many productive years working together in the physics laboratory. A short time after they discovered radium, Pierre was killed by a horse-drawn wagon in 1906. Marie was stunned by this horrible misfortune and endured heartbreaking anguish. Despondently she recalled their close relationship and the joy that they had shared in scientific research. The fact that she had two young daughters to raise by herself greatly increased her distress.Curie's feeling of desolation finally began to fade when she was asked to succeed her husband as a physics professor at the Sorbonne. She was the first woman to be given a professorship at the world-famous university. In 1911 she received the Nobel Prize in chemistry for isolating radium. Although Marie Curie eventually suffered a fatal illness from her long exposure to radium, she never became disillusioned about her work. Regardless of the consequences, she had dedicated herself to science and to revealing the mysteries of the physical world.16) Marie had a bright mind and a ________ personality.(A) Strong (B) lighthearted (C) Humorous (D) StrangeAns: B17) When she learned that she could not attend the university in Warsaw, she felt ______ .(A) Hopeless (B) Annoyed (C) Depressed (D) WorriedAns: B18) Marie ______ by leaving Poland and traveling to France to enter the Sorbonne.(A) Challenged authority (B) Showed intelligence(C) Behaved (D) Was distressedAns: A19) _____ she remembered their joy together.(A) Dejectedly (B) Worried (C) Tearfully (D) HappilyAns: A20) Her ________ began to fade when she returned to the Sorbonne to succeed her husband.(A) Misfortune (B) Anger (C) Wretchedness (D) DisappointmentAns: C21) Even though she became fatally ill from working with radium, Marie Curie was never(A) Troubled (B) Worried (C) Disappointed (D) SorrowfulAns: C22) ___ teachers of this school are punctual.a) ab) anc) thed) no articleAns: cExplanationTalks of a specific noun, hence the.23) My book has become ________ best seller in academic English preparation.a) ab) anc) thed) no articleAns: cExplanation:Talks about a specific condition; there cannot be more than one noun when we use words like best, ideal, perfect, absolute, only, hence the.24) Can anyone give me ______ hand?a) ab) anc) thed) no articleAns: aExplanation:Doesn't mention any specific noun, hence a.
