Solution:

\table , \Men, \Women, \children;\Work,3,2,1;\Numbers,20,30,36

Ratio of wages = (3 x 20): (2 x 30): (1 x 36) = 5 :5 :3
Total wages of men =

5/{13}

× 780 = ₹ 300
∴ Wages of a man = ₹ 15
Similarly, wages of woman = ₹ 10
and wages of child = ₹ 5
Total wages of 15 men, 21 women and 30 children
= 15 x 15 + 21 x 10 + 30 x 5 = 585
Total wages for 2 weeks = ₹ 1170
