3 Boys and 7 girls can do a piece of work in 5 days, while 2 boys and 8 girls can do it in 6 days. Boys and girls are paid according to their output. If the daily wage of a boy is Rs. 30, then the ratio of daily wages of a boy and a girl will be?

(3B + 7G) × 5 = (2B + 8G) × 6
15B + 35G = 12B + 48G
3B = 13G
B : G = 13 : 3
