explanation
1. (5) let population of state C in 2005 and 2006 be 2x and 3x respectively
literate population in 2005 is= 78/100* 2x
literate population in 2006 is = 81/100*3x
required ratio= 78* 2x : 81 * 3x = 52 : 81
2. (3) Average literate population = 1200000/100 * (72+81+81+65+93+88/6)
3. (2) Required %= 75- 65/ 65* 100= 15.38=15
= 12.1 lakhs
5.(1) Average % of literate population= 69+85+84+69+94+91/6= 82
required average literate population= 82% of 12.5 lakhs = 82*12.5/100= 10.25 lakhs
