Eric had $85, Ahmad had $30 and Ian had twice the total amount of money Eric and Ahmad had. How much must Ian give to Eric and Ahmad so that each of them has an equal amount of money?
- Eric
- Ahmad
(a)
Total amount that Eric and Ahmad had
= 85 + 30
= $115
Amount that Ian had
= 2 x 115
= $230
Total amount that the 3 boys had
= 115 + 230
= $345
Amount that each of them must have so that each of them has an equal amount of money
= 345 ÷ 3
= $115
Amount that Ian must give to Eric
= 115 - 85
= $30
(b)
Amount that Ian must give to Ahmad
= 115 - 30
= $85
Answer(s): (a) $30; (b) $85
