Answer:
£380
Explanation:
Consider the initial win of £4750
Sum the parts of the ratio, 1 + 4 = 5 parts
Divide the win by 5 to find the value of one part of the ratio.
£4750 ÷ 5 = £950 ← value of 1 part of the ratio
Thus Jim's share is £950
Sum the parts of the ratio shared in his family, 2 + 6 + 2 = 10 parts
Divide his share by 10 to find the value of one part
£950 ÷ 10 = £95 , thus
2 parts = 2 × £95 = £190 ← sons share
6 parts = 6 × £95 = £570 ← wife's share
£570 - £190 = £380
Wife gets £380 more than the son
