Divide Rs. 760 among 4 men, 3 women and 5 children
so that each man may have double the share of women
and each woman may have three times the share of a
child. Find the share of 1 child.
a) Rs. 50 b) Rs. 20
c) Rs. 120 d) Rs. 60
ans: b) rs. 20
Suppose the share of a child = Rs. 1
∴1 woman would get Rs. 3 and a man would Rs. 6
Now 4 men get = 6 x 4 = Rs. 24
3 women get = 3 x 3 = Rs.9
and 5 children get = 1 x 5 = Rs. 5
Now divide 760 in the ratio 24 : 9 : 5
