34 of his pay and George saved
37 of his pay. Ahmad saved $170 more than George in a month. How much did George save in a month?

Ahmad |
George |
Before |
4x7 = 28 u |
7x4 = 28 u |
Change |
- 3x7 = - 21 u |
- 3x4 = - 12 u |
After |
1x7 = 7 u |
4x4 = 16 u |
The amount that Ahmad and George each earned in a month is the same. Make the amount the same. LCM of 4 and 7 is 28.
Amount that Ahmad saved more than George
= 21 u - 12 u
= 9 u
9 u = 170
1 u = 170 ÷ 9 = 170
Amount that George saved in a month
= 12 u
= 12 x 170
= $2040
Answer(s): $2040
