Seth had $91, Simon had $21 and Oliver had five times the total amount of money Seth and Simon had. How much must Oliver give to Seth and Simon so that each of them has an equal amount of money?
- Seth
- Simon
(a)
Total amount that Seth and Simon had
= 91 + 21
= $112
Amount that Oliver had
= 5 x 112
= $560
Total amount that the 3 boys had
= 112 + 560
= $672
Amount that each of them must have so that each of them has an equal amount of money
= 672 ÷ 3
= $224
Amount that Oliver must give to Seth
= 224 - 91
= $133
(b)
Amount that Oliver must give to Simon
= 224 - 21
= $203
Answer(s): (a) $133; (b) $203
