Answer & Explanation 2. 2; 3. 3; 4. 5; 5. 1; 6. 3 7. 2 8. 3 9. 2 10. 1
Females = 5 + 8 + 8 = 21
Total males = 120, Females (one cate) = 20 + 12 + 25 = 57
Diff = 120 – 57 = 63
M + F = 15, F = 8
M = 7,
Ratio = 15 : 7
Total males = 40 + 18 + 25 + 15 + 7 + 7 = 112
Female(total) = 80,
Male (alt-3 cate) = 10 – 2 = 8
% = 8/80 * 100 = 10%
