Japheth had $77, Billy had $21 and Oscar had twice the total amount of money Japheth and Billy had. How much must Oscar give to Japheth and Billy so that each of them has an equal amount of money?
- Japheth
- Billy
(a)
Total amount that Japheth and Billy had
= 77 + 21
= $98
Amount that Oscar had
= 2 x 98
= $196
Total amount that the 3 boys had
= 98 + 196
= $294
Amount that each of them must have so that each of them has an equal amount of money
= 294 ÷ 3
= $98
Amount that Oscar must give to Japheth
= 98 - 77
= $21
(b)
Amount that Oscar must give to Billy
= 98 - 21
= $77
Answer(s): (a) $21; (b) $77
