| Helen | Ali | |
| At first | 4u | 4u – 248 |
| Helen gave Ali 3/4 = 3u | 4u – 3u = 1u | 4u – 248 + 3u = 7u – 248 |
7u – 248 – 364 = 1u
6u = 612
u = 102
At first, Ali had (4u – 248) = 408 – 248 = 160

At first —
Helen : 4u + 248
Ali : 4u
After —
Helen : 4u + 248 – 3u – 186 = 1u + 62
Ali : 4u + 3u + 186 = 7u + 186
7u + 186 ——- 1u + 62 + 364 = 1u + 426
1u ——- (426 – 186)/(7 – 1) = 40
4u ——- 4 x 40 = 160
Ans : 160 marbles.
