Answer & Explanation

1.(4) Required number of students = 72 + 45+ 54 + 27 = 198
2.(3) Required number of students = 54 + 27 + 32 + 56= 169
3.(5) Required percentage= (27 + 54 + 27 + 27 + 28 + 112 + 84 + 56)/(270 +560)x 100%= 50%
4.(1) Required number of students = 48 + 16 + 32 + 84 + 28 + 84= 292
5.(2) Required ratio = (64+ 48+ 80+ 32) : (84+ 112 + 84+ 56)= 224:336=2:3
6. (4)Required ratio = (108+90+63+54+54+54+27+27)/720x 100% = 661/4 %
7.(5) 43%
8. (5) Required percentage = (364 + 312 + 130)/3120 * 100 = 26
9. (3) Required ratio = 260 : 770 = 26 : 77
10. (2) Required percentage = 130/364 * 100 = 35.71
11. (4)Total number of boys who are enrolled in Dancing = 364 + 156 + 140 + 208 = 868
