Explanation:
1.       (B) Graduate male population of state A
= 24 x 16/100 x 7/12 lakh = 2.24 lakh
12th male population of state A
= 32 x 15/100 x 7/16 lakh = 2.1 lakh
Required difference = (2.24 – 2.1) lakh = 14000
2.       (D) Graduate female population of state E
= 24 x 20/100 x 7/16 lakh = 2.1 lakh
12th female population of state D
= 32 x 12/100 x 7/12 lakh = 2.24 lakh
Required ratio = (2.1 : 2.24)
= 210 : 224 = 15 : 16
3.       (C) Graduate female population of state C
= 24 x 15/100 x 4/9 = 1.6 lakh
12th female population of state C
= 32 x 18/100 x 5/9 = 3.2 lakh
Required percentage = 1.6/3.2 x 100% = 50%
4.       (A) 12th pass male population of state C
= 32 x 18/100 x 4/9 = 2.56 lakh
Required percentage = 2.56/32 x 100% = 8%
5.       (E) Graduate male population of state E
= 24 x 20/100 x 9/16 = 2.7 lakh
12th pass female population of State E
= 32 x 19/100 x 10/ 19 = 3.2 lakh
Required ratio = 27 : 32


Having only adequate water supply =25/100 x 1800 = 450 
Having only proper electric supply =15/100 x 1800 = 270
Having only proper education facilities =7/100 x 1800 = 126
Having only telecommunication services= 12/100 x 1800 = 216
Having only health care services =16/100 x 1800 = 288
Having water and electric supply= 6/100 x 1800 = 108
Having proper water supply, electric supply and health care services                     
=8/100 x 1800 = 144
Having proper electric supply telecommunication and health care services         
=5/100 x  1800 = 90
Having all the facilities =6/100 x 1800 = 108     
                                                                                                                     
6.       (D) Number of villages with adequate water supply
= 450 + 108 + 144 + 108 = 810
7.       (A) Number of villages with adequate supply of water and electricity
= 109 + 144 + 108 = 360
8.       (D) Number of villages with proper supply of electricity 
= 270 + 108 + 144 + 90 + 108 = 720
Number of villages not having proper electric supply
= 1800 – 720 = 1080
9.       (B) Number of villages with only proper education facilities = 126


10.   (D) Number of villages with all the facilities = 108
