|
After |
3 u |
+ 123 |
2x5 =
10 u |
|
205 ÷ 5 = 41
3 x 41 = 123
8 x 41 = 328
Total amount that Vaidev and George had at first
= 8 u + 328 + 15 u
= 23 u + 328
23 u + 328 = 1225
23 u = 1225 - 328
23 u = 897
1 u = 897 ÷ 23 = 39
Amount that Vaidev had at first
= 8 u + 328
= 8 x 39 + 328
= 312 + 328
= $640
Answer(s): $640
