35 of his pay and Sean saved
37 of his pay. Ken saved $200 more than Sean in a month. How much did Sean save in a month?

Ken |
Sean |
Before |
5x7 = 35 u |
7x5 = 35 u |
Change |
- 3x7 = - 21 u |
- 3x5 = - 15 u |
After |
2x7 = 14 u |
4x5 = 20 u |
The amount that Ken and Sean each earned in a month is the same. Make the amount the same. LCM of 5 and 7 is 35.
Amount that Ken saved more than Sean
= 21 u - 15 u
= 6 u
6 u = 200
1 u = 200 ÷ 6 = 200
Amount that Sean saved in a month
= 15 u
= 15 x 200
= $3000
Answer(s): $3000
