Eric |
Vaidev |
Before |
6x7 = 42 u |
7x6 = 42 u |
Change |
- 5x7 = - 35 u |
- 3x6 = - 18 u |
After |
1x7 = 7 u |
4x6 = 24 u |
The amount that Eric and Vaidev each earned in a month is the same. Make the amount the same. LCM of 6 and 7 is 42.
Amount that Eric saved more than Vaidev
= 35 u - 18 u
= 17 u
17 u = 50
1 u = 50 ÷ 17 = 50
Amount that Vaidev saved in a month
= 18 u
= 18 x 50
= $900
Answer(s): $900
