ANSWERS

1. 3; MP A slight look is sufficient to answer this question.

2. 2; Reqd difference

 =  ((37-3) + (39-28) + (121-13) + (21-10)+(24-3))/5

 =  185/5 = 37

3. 4; Total P cases in Bihar (2002) = 121

 Total P cases in India (2002) = 1600

 Reqd answer = 121/1600 × 100 = 7.5% (approx)

4. 3; Reqd percentage = (3+27)/24 × 100 = 125%

5. 4; Total P cases in India (2001) = 268

 Total P cases in the given states (2001) = 36

 Hence, reqd. ratio = 36/(268 - 36) = 36/232 = 9 : 58.

6. 1; i/e  = 1.2

 e = i/1.2 = 48/1.2  = 40

7. 2; For A, in years 2007 and 2009, import > export

 For B, in all six years, import < export

 Ratio = 2/6 = 1/3 = 1:3

8. 2; For A, in 2006, i/e = 0.64

 Income = 0.64 × 75 = 48

 For B, in 2007, i/e  = 0.8

 i = 0.8 × 75 = 60

 % = 48/60 × 100 = 80%

9. 5; Data is not sufficient.

10. 5; In 2004,  iB / eB = 0.8 = 4/5 

 In 2007, iA / eA  = 1.2 = 6/5 

        eA / iA    = 5/6  

 Ratio between them =  (4/5)/(5/6) = 24:25
