1 .
 Answer : Option A Explanation : $Male_{A+B}$ = = 30000 {$21\over 100$ x $11\over 15$ + $18\over 100$ x $11\over 18$}= 300 (15.4 + 11)= 300x 26.4 = 7920
2 .
 Answer : Option D Explanation : $Male_D$ = 30000 x $12 \over 100$ x $11\over 24$$Female_C$ = 30000 x $17 \over 100$ x $5\over 17$Ratio = $11\over 10$ = 11 : 10
3 .
 Answer : Option C Explanation : $Male_B$ = 30000 x $18\over 100$ x $11\over 18$ = 3300$Female_E$ = 30000 x $22\over 100$ x $4\over 11$ = 2400Reqd % = $3300 - 2400 \over 2400$ x 100 = $900 \over 24$ = 37.5 %
4 .
 Answer : Option B Explanation : Total Females = $30000\over 100$ x [21 x $4\over 15$ + 18 x $7\over 18$ + 17 x $5\over 17$ + 12 x $13\over 24$ + 22 x $4\over 11$ + 10 x $11\over 30$]= 300 [5.6 + 7 + 5 + 6.5 + 8 + $11\over 3$]= 300 (32.1 + $11\over 3$ )= 100 x 107.3 = 10730Reqd % = $10730 \over 30000$ x 100 = 35.76 $\cong$ 36 %
5 .
 Answer : Option D Explanation : $D_{Total}$ = 30000 x $12\over 100$ = 3600$A_{Female}$ = 30000 x $21\over 100$ x $4\over 15$ = 1680 Required fraction = $1680 \over 3600$ = $7\over 15$
6 .
 Answer : Option D Explanation : Total Males = $9600000\over 10000$ [16 × 52 + 15 × 57 + 24 × 51 + 9 × 48 + 7 × 47 + 17 × 53 + 12 × 50]= 960 × [832 + 855 + 1224 + 432 + 329 + 901 + 600]= 960 × 5173 = 4966080Average = $4966080\over 7$ = 709440
7 .
 Answer : Option C Explanation : $Illiterate_A$ = 9600000 x $16\over 100$ x $64\over 100$ = 983040$Illiterate_A$ = 9600000 x $16\over 100$ x $36\over 100$ = 552960Difference = 983040 - 552960 = 430080
