Simon and Sean earned the same amount each month. Simon saved
23 of his pay and Sean saved
27 of his pay. Simon saved $200 more than Sean in a month. How much did Sean save in a month?

Simon |
Sean |
Before |
3x7 = 21 u |
7x3 = 21 u |
Change |
- 2x7 = - 14 u |
- 2x3 = - 6 u |
After |
1x7 = 7 u |
5x3 = 15 u |
The amount that Simon and Sean each earned in a month is the same. Make the amount the same. LCM of 3 and 7 is 21.
Amount that Simon saved more than Sean
= 14 u - 6 u
= 8 u
8 u = 200
1 u = 200 ÷ 8 = 200
Amount that Sean saved in a month
= 6 u
= 6 x 200
= $1200
Answer(s): $1200
