Explanation:

1.       (B) Graduate male population of state A

= 24 x 16/100 x 7/12 lakh = 2.24 lakh

12^th 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

12^th 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

12^th 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) 12^th 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

12^th 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
