Question

At first. the ratio of Sean’s savings to Eugene’s savings was 3:7. After each of them bought a similar laptop for $1488. the ratio of Sean’s savings to Eugene’s savings became 1:4. What was the total sum of savings Sean and Eugene had at first?

Answer

3u – 1488 ——- 1p
7u – 1488 ——- 4p = 4 x (3u – 1488) = 12u – 5952
1u = (5952 – 1488)/(12 – 7) = 892.80
3u + 7u = 1u = 10 x 892.80 = 8928

Ans : $8928.

This is  a Before After question.

   Before  Transfer  After   Ratio
Sean 3u -1488 3u – 1488 1
Eugene  7u -1488 7u – 1488 4
Total 10u      

(3u – 1488) /1 = (7u – 1488) / 4

12u – 5952 = 7u – 1488

12u – 7u = 5952 – 1488

5u = 4464

10u = 4464 ×2 = 8928
