Vaidev and Zane had $925 altogether. After Vaidev spent
13 of his money and Zane spent
45 of his money, Vaidev was left with five times as much money as Zane. How much money did Zane have at first?

| Before |
3x5 =
15 u |
5x2 =
10 u |
$925 |
| Change |
- 1x5 =
- 5 u |
- 4x2 =
- 8 u |
|
| After |
2x5 =
10 u |
1x2 =
2 u |
|
Comparing Vaidev
and Zane in the end |
5x2 =
10 u |
1x2 =
2 u |
|
The amount that Vaidev had in the end is repeated. Make the amount that Vaidev had in the end the same. LCM of 2 and 5 is 10.
Total amount that Vaidev and Zane had at first
= 15 u + 10 u
= 25 u
25 u = 925
1 u = 925 ÷ 25 = 37
Amount that Zane had at first
= 10 u
= 10 x 37
= $370
Answer(s): $370
