6The work done by a man, a woman and a child is in the ratio of 3: 2: 1. There are 20 men, 30 women and 36 children in a factory. Their weekly wages amount of Rs. 780, which is divided in the ratio of work done by the men, women and children. What will be the wages of 15 men, 21 women and 30 children for 2 weeks?

Option : C
Explanation :
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 20 men = 5/13 =Rs.300
∴ Wages of a man = Rs.15.
Similarly, wages of 30 women (5/30) x 780 = Rs.300
Wages of a woman = Rs.10
and wages of 36 children (3/13) x 780 = Rs.180
Wages of a child = Rs.5
∴ Total wages of 15 men, 21 women and 30 children
= 15 x 15 + 21 x 10 + 30 x 5
= Rs.585
∴ Total wages for 2 weeks = Rs.1170.
