3 u |

$324 |
The total amount that Vincent and Vaidev had remains unchanged.
Total amount in the end
= 3 u + 1 u
= 4 u
4 u = 324
1 u = 324 ÷ 4 = 81
Amount that Vaidev has in the end
= 3 u
= 3 x 81
= $243
Amount that Vincent has in the end
= 1 u
= $81
3 p = 1 u = 81
1 p = 81 ÷ 3 = 27
Amount that Vincent gave to Vaidev
= 1 p
= 1 x 27
= $27
Amount that Vaidev had at first
= 243 - 27 + 15
= $231
Answer(s): $231
