Question 1132275
<br>
A has an income of 1200; and the ratio of incomes is A:B:C = 5:4:3.  So B has an income of 960 (4/5 of 1200) and C has an income of 720 (3/5 of 1200).<br>
A saves 80 of his income of 1200, so he spends 1120; and the ratio of spending is A:B:C = 8:5:4.  So B spends 700 (5/8 of 1120) and C spends 560 (4/8 of 1120).<br>
So B's saving is 960-700 = 260; C's saving is 720-560 = 160.
