Answers and Explanations
1. (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.
