An equal number of chocolate bars were distributed to 6 boys and 9 girls. Each boy then gave
23 of her share of chocolate bars to the girls. As a result, each girl received 4 more chocolate bars.
- How many chocolate bars did each boy have left?
- Find the total number of chocolate bars each girl had after receiving more chocolate bars from the boys.
(a)
Number of chocolate bars that the boys gave to the girls
= 9 x 4
= 36
Number of chocolate bars that each boy gave to the girls
= 36 ÷ 6
= 6
Number of chocolate bars that each boy had at first = 3 u
Number of chocolate bars that each boy gave away = 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Number of chocolate bars that each boy left
= 3 u - 2 u
= 1 u
= 3
(b)
Number of chocolate bars that each girl had in the end
= 3 u + 4
= 3 x 3 + 4
= 9 + 4
= 13
Answer(s): (a) 3; (b) 13
