Question

Answer

(a)
9 – 1 = 8
264/8 = 33 (Alvin’s savings in the end)
33 x 9 = 297 (Bernard’s savings in the end)

Alvin’s savings : Bernard’s savings
3u : 11u

Assuming both spent 1p each,
3u – 1p ——- 33
11u – 1p ——- 297
11u – 3u = 8u ——- 297 – 33 = 264
1u ——- 264/8 = 33

After Alvin gave 1/10 of his saving to Bernard.
Alvin : 3u ——- 3 x 33 = 99
Bernard : 11u ——- 11 x 33 = 363

1 – (1/10) = 9/10 ——– 99
1/10 ——- 99/9 = 11
10/10 = 10 x 11 = 110 (Alvin’s savings at first) (b)
363 – 11 = 352 (Bernard’s savings at first)

The ratio of Alvin’s savings to Bernard’s savings at first is 110 : 352 = 5 : 16.

Ans : (a) 5 : 16; (b) $110.
