In a school having roll strength 286, the ratio of boys and girls is 8 : 5. If 22 more girls get admitted into the school, the ratio of boys and girls becomes

A. 12 : 7

B. 10 : 7

C. 8 : 7

D. 4 : 3

Answer: Option D

Solution(By Examveda Team)

Boys : girls = 8 : 5 (let the boys = 8x, girl = 5x)
Total strength = 286
8x + 5x = 286
13x = 286
Or, x = $$\frac{{286}}{{13}}$$ = 22
Boys = 176 and girls = 110
22 more girls get admitted then number of girls become
(5x + 22) = 110 + 22 = 132
Now, new ratio of boys and girls = 176 : 132 = 4 : 3

    boys = 8x = 8*22 = 176
    girls = 5x = 5*22 = 110
