1 .
 Answer : Option D Explanation : Population of village B in 1995 = 5000 x $16over 13$ $cong$ 6150Population of village B in 1996 = 6150 x $110over 100$ $cong$ 6750 Population below poverty line = 52% of 6750 $cong$ 3500
2 .
 Answer : Option A Explanation : Population of village D in 1995= 9000 × $17\over 15$= 10,200Population of village D in 1997= 10200 × $110\over 100$=11220Population of village G in 1997= 9000 × $95\over 100$= 8550Total population of villages D and Gin 1997= 11220 + 8550 = 19770
3 .
 Answer : Option D Explanation : Population of village F below poverty line = 5500 x $13\over 100$ x $49\over 100$ $\cong$ 3500
4 .
 Answer : Option C Explanation : Population of village F in 1995 = 1520 x $100 \over 37$ x $13\over 8$ = 6500
5 .
 Answer : Option B Explanation : Population of village C below poverty line = 2000 x $38 \over 100$ = 760Population of village E below poverty line = $2000\over 8$ x 18 x $46\over 100$ = 2070Reqd.Ratio = $760 \over 2070$ = 76 : 207
6 .
 Answer : Option D Explanation : Number of boys in school R and U together= $2000 \times 72.5\over 100$ + $1000 \times 82.5\over 100$ = (1450 + 825) = 2275Required percentage = $2275\over 3000$ x 1000 = 75.83%
7 .
 Answer : Option D Explanation : Number of boys in school T = $1250\times 60\over100$ = 750
8 .
 Answer : Option A Explanation : Required percentage = $2000\over 2250$ x 100 = 89
9 .
 Answer : Option B Explanation : Required percentage = $1\over 2$ x $2500\times60\over100$ + $3000\times 55\over 100$= $1\over 2$ (1500 + 1650)= 1575
10 .
 Answer : Option C Explanation : Required ratio = $2500\times40\over100$ : $3000 \times 45 \over 100$= 25 x 40 : 30 x 45 = 20 : 27
