Harry had $75, Ethan had $33 and John had thrice the total amount of money Harry and Ethan had. How much must John give to Harry and Ethan so that each of them has an equal amount of money?
- Harry
- Ethan
(a)
Total amount that Harry and Ethan had
= 75 + 33
= $108
Amount that John had
= 3 x 108
= $324
Total amount that the 3 boys had
= 108 + 324
= $432
Amount that each of them must have so that each of them has an equal amount of money
= 432 ÷ 3
= $144
Amount that John must give to Harry
= 144 - 75
= $69
(b)
Amount that John must give to Ethan
= 144 - 33
= $111
Answer(s): (a) $69; (b) $111
