34 of his pay and Carl saved
37 of his pay. Simon saved $160 more than Carl in a month. How much did Carl save in a month?

Simon |
Carl |
Before |
4x7 = 28 u |
7x4 = 28 u |
Change |
- 3x7 = - 21 u |
- 3x4 = - 12 u |
After |
1x7 = 7 u |
4x4 = 16 u |
The amount that Simon and Carl each earned in a month is the same. Make the amount the same. LCM of 4 and 7 is 28.
Amount that Simon saved more than Carl
= 21 u - 12 u
= 9 u
9 u = 160
1 u = 160 ÷ 9 = 160
Amount that Carl saved in a month
= 12 u
= 12 x 160
= $1920
Answer(s): $1920
