Answer & Explanation

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.
