An equal number of chocolate bars were distributed to 7 boys and 8 girls. Each boy then gave
45 of her share of chocolate bars to the girls. As a result, each girl received 7 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
= 8 x 7
= 56
Number of chocolate bars that each boy gave to the girls
= 56 ÷ 7
= 8
Number of chocolate bars that each boy had at first = 5 u
Number of chocolate bars that each boy gave away = 4 u
4 u = 8
1 u = 8 ÷ 4 = 2
Number of chocolate bars that each boy left
= 5 u - 4 u
= 1 u
= 2
(b)
Number of chocolate bars that each girl had in the end
= 5 u + 7
= 5 x 2 + 7
= 10 + 7
= 17
Answer(s): (a) 2; (b) 17
