1 Ans 01. (c) The author of paragraph probably uses the expression three-fold power to emphasize the contrast between loss of money, loss of other resources, and loss of wildlife Ans 02.(d) From the context, the word venial in paragraph two most nearly means trivial. Ans 03. (a)the paragraph apparently imply that there is no source from which wildlife, once exterminated, can be replaced Ans 04. (c) It can be inferred that the spendthrift in paragraph one and the poor settler mentioned in paragraph two are alike in that they are more concerned with the present than the future. Ans 05.(d)A majority of 67% women are favouring Congress (I) according to the data given. Ans 06. (a)72% men, i.e., a big majority favours Shiv Sena and BJP Alliance. Ans 07.(b)If the alliance splits up before the elections, what will happen cannot be definitely ascertained because it is not clear from the data how much support Shiv Sena gains and how much is the share of BJP. However, Congress (I), which has a support of 40% voters may get majority of seats, after the split. Ans 08.(b) Since the number is greater than the number obtained on reversing the digits, so the ten's digit is greater than the unit's digit. Let ten's and unit's digits be 2x and x respectively. Then, (10 x 2x + x) - (10x + 2x) = 36 9x = 36 x = 4. Required difference = (2x + x) - (2x - x) = 2x = 8. Ans 09.(d) ( )/2 = 8 ( )/2 = 10 ( )/2 = 6. Ans10. (d) 100 cm is read as 102 cm. A 1 = (100 x 100) cm 2 and A 2 (102 x 102) cm 2. (A 2 - A 1) = [(102) 2 - (100) 2 ] = ( ) x ( ) = 404 cm 2. Percentage error = 404x 100 % = 4.04% Ans 11.(a)We know that (A U B) = A + B - (A n B), where (A U B) represents the set of people who have enrolled for at least one of the two subjects English or Hindi and (A n B) represents the set of people who have enrolled for both the subjects English and Hindi. (A U B) = A + B - (A n B) => (A U B) = = 95%

2 That is 95% of the students have enrolled for at least one of the two subjects English or Hindi. Therefore, the balance (100-95)% = 5% of the students have not enrolled for either of the two subjects. Ans 12. (b) Suppose the man works overtime for x hours. Now, working hours in 4 weeks = (5 x 8 x 4) = x x x 3.20 = x = = 48 x = 15. Hence, total hours of work = ( ) = 175. Ans 13. (c)when Darwin arrived on the scene, the thought of development had been thought over but was not a proved one. Ans 14. (b) According to the vision of Darwin, the animal world has been marked by struggle for survival. Ans 15. (a) The expression survival of the fittest means that the powerful shall live and the weak shall die. Ans 16. (c)in cold climate only those animals can survive who have hair. Ans 17. (c)both the statements are correct. Appointment of any person who heads the country s anticorruption watchdog unit can be challenged by public interest litigations (PILs) but it should be kept in mind that such PILs will be raused only against some mal-election of CVC. As regards statement no. 2, Sushma Swaraj raised a voice of dissent against his selection because of his questionable record. Ans 18. (b)if any person is appointed as CVC, then impeccable integrity is neither an eligibility criterion nor mandatory for such appointments as constitutional norms of the date. Ans 19. (b)npt classified the world into two categories: nuclear weapon states (NWS) and non-nuclear weapon states (NNWS) and that is the main reason why Govt of India has called it discriminatory. Ans 20. (c)both the statements stated are correct. Ans 21. (d) Let the length of the field be X m and let the number of fences he get be Y. Then as per the plan if the farmer tries to arrange them at a distance of 6m each, then there shall be 5 short. Also if he tries to place them 8m apart, then the number of fences required shall be perfectly matching the number available. Hence the equations shall look like: (X / 6) + 1= Y + 5; X / = Y. Solving Y = 16, also the value of X = 120m. Ans 22. (a) Total quantity of petrol = litres consumed in 3 years = litres

3 = litres 51 Total amount spent = Rs. (3 x 4000) = Rs Average cost = Rs x 51 = Rs = Rs Ans 23.(a) Gain = 20% I. Profit = (S.P.) - (C.P.) = Rs. 40. Thus, I give the Ans. But, II does not give the Ans. Correct Ans is (A). Ans 24.(c) The differences between the amount invested in raw material and the value of sales of finished goods for various years are: For 1995 = Rs. ( ) lakhs = Rs. 80 lakhs. For 1996 = Rs. ( ) lakhs = Rs. 75 lakhs. For 1997 = Rs. ( ) lakhs = Rs. 125 lakhs. For 1998 = Rs. ( ) lakhs = Rs. 70 lakhs. For 1999 = Rs. ( ) lakhs = Rs. 75 lakhs. For 2000 = Rs. ( ) lakhs = Rs. 40 lakhs. Clearly, maximum difference was during Ans 25.(d) Required percentage = 600 x 100 % ( ) = 48.78% 49%. Ans 26.(d) Required difference 1 = Rs. x ( ) 6-1 x ( ) lakhs = Rs. - lakhs 6 6 = Rs. ( ) lakhs = Rs lakhs. Ans 27.(b) The percentage change in the amount invested in raw-materials and in the value of sales of finished goods for different years are:

4 Percentage change in Amount invested in raw-material: For 1996 = ( ) x 100 % = 87.5%. 120 For 1997 = ( ) x 100 % = 66.67%. 225 For 1998 = ( ) x 100 % = -12%. 375 For 1999 = ( ) x 100 % = 59.09%. 330 For 2000 = ( ) x 100 % = -20%. 525 Percentage change in value of sales of finished goods: For 1996 = ( ) x 100 % = 50%. 200 For 1997 = ( ) x 100 % = 66.7%. 300 For 1998 = ( ) x 100 % = -20%. 500 For 1999 = ( ) x 100 % = 50%. 400 For 2000 = ( ) x 100 % = %. 600 Thus, the percentage difference is same during the year Ans 28.(a) The percentage increase in the amount invested in raw-materials as compared to the previous year, for different years are: For 1996 = ( ) % = 87.5%. 120 For 1997 = ( ) % = 66.67%. 225 For 1998 there is a decrease. For 1999 = ( ) % = 59.09%. 330 For 2000 there is a decrease. There is maximum percentage increase in Ans 29. (d)black Seed gives Blue flower or Red flower. White seed gives White flower or red flower. Now statement 1 says plants with white flowers are 10. Nothing can be said now with this statement. Statement 2 says number of plants with red flowers is 70. Again nothing can be said. On combining we get 10 plants with white flowers and 70 with Red flowers. So plants with Blue flowers should be 20 (As total number of plants is 100). Now blue flowers shall come from Black seeds only. So there are at least 20 Black seeds used. 10 white flowers can come only from white seeds. So at least 10 white seeds have been used. Now the remaining 70 red could have come from either black or white seeds. So data is insufficient. Hence Ans is (d).

5 Ans 30. (d) Parasitic word best describes the fungus as depicted in the passage. Ans 31. (d) The passage states all of the following about fungi, exceptthey are poisonous to resin producing plants. Ans 32. (a) The author s statement that you are watching a fungus eating, is best described as figurative. Ans 33. (d)the author is primarily concerned with describing the actions of fungi.

Ans 43.(b) There are 3 types of faces, 3 types of bodies, 3 types of hands and 3 types of legs, each of which is used only once in a single row. So, the features which have not been used in the first two figures of the third row would combine to produce the missing figure. Ans 44.(c) The adjacent faces to the face which 3 points have 2, 1, 4 and 6 points. Hence on the face which is opposite to the face which contains 3 points, there will be 5 points. Ans 45.(b) When the sheet in fig. (X) is folded to form a cube, then the face bearing a dot lies opposite to one of the shaded faces. Therefore, the cube shown in fig. (2) which has both the shaded faces adjacent to the face bearing the dot, cannot be formed. Hence, the cubes shown in figures (1), (2) and (4) can be formed. Ans 46.(d)

7 At 4 o'clock, the hands of the watch are 20 min. spaces apart. To be in opposite directions, they must be 30 min. spaces apart.
