Step-by-step explanation:
The question is incomplete. The complete question is:
David & Dan share a lottery win of £9900 in the ratio 3 : 2. David then shares his part between himself, his wife & their son in the ratio 4 : 4 : 2. How much more does his wife get over their son?
Solution:
David & Dan share a lottery win of £9900 in the ratio 3 : 2. The total ratio is 3 + 2 = 5
The amount that David got would be
3/5 × 9900 = £5940
Therefore, £5940 was shared in the ratio of 4 : 4 : 2. The total ratio is 4 + 4 + 2 = 10
The amount that his wife gets is
4/10 × 5940 = £2376
The amount that his son gets is
2/10 × 5940 = £1188
The amount that his wife gets over their son is
2376 - 1188 = £1188
