(B): Need to compare (48/180), (58/190), (60/200), (60/210) which yields B as the answer. 2. (A): In 2010 the percentage share is 30% in 2014 it is 14.28% the difference is 15.72%. 3. (C): Comparing 2013 and 2014 for 2013: 22/18, 2014: 20/40 2013 is therefore more. 4. (D): 115/5=23 5. (A): 5700/ 8500 = 2/3 Therefore Passed / Appeared = (18*2)/ (22* 3) = 6:11 6. (B): We need to compare 34/45, 26/30, 18/24, 30/36…where 26/30 is highest. 7. (B): (5700* 34/100) – (8550 * 18/100) = 399 8. (A): (15/45) * 100 = 33.33% 9. (D): A=60% = 3/5 if profit is 3 exp is 5 revenue = 8, B=50% = 1/2 if profit is 1 exp is 2 revenue =3. Make both revenues equal by multiplying with 3 for A and multiplying with 8 for B. Now expenses will be in the ratio of 15: 16. 10. (B): In 2014 Ap= 25% = 1/4 which means if profit is 1 exp is 4 revenue is 5. In 2015 Bp = 20% = 1/5 which means if profit is 1 exp is 5 revenue is 6.
- 8. 5 unit = 90 lacs B15 revenue – Aexpenses = 6-4= 2 units, therefore 2 units = 2*18= 36lac 11. (C): 60 % = 3/5 if profit is 3 expenses are 5 revenue is 8. (5/8) *100 = 62.5% 12. (B): 315-250=65; 65/250 = 26% 13. (D): We need to compare 40/100, 30/70, 45/50, 30/30 ; Aatam Nirbhar is highest 14. (C): (130/3) / (260/3)= 1/2 which equals to 50%. 15. (D): Cannot be determined we do not the actual number of volunteers at the two NGO’s. 16. E: A can be 5 and -5 and B can 3 and -3 so we do not get a definite anserwer even after combining 17. C: 0< -2a which means a is negative 18. E: both I and II are same equations. 19. B: whether THREE is greater equal or less than ONE is dependent solely on the value of TWO only. 20. E: Combining I and II : A+B is less than 6 but whether A+B > 5 is not definite. 21. E: Both Feb and March will have odd number of days in a leap year. 22. E: Both statements mean the same thing. 23. A: Statement I gives definite answer as 4, Statement II will give many answers. 24. C: The top three were Dona, Heena and Mona 25. E: Cost will vary between 13 and 20 since the exact cost is not known so we cannot comment on profit. 26. A: Statement II does not provide a unique value for the variable. 27. C: Combining the two T is aunt of K. 28. E: Both the statements are required.
- 9. 29. E: Combining the two will give C sits immediate left of A. A and B faces center and C faces outside. 30. B: Combining I and III will give a definite answer. Manu is grandson.
