An equal number of chocolate bars were distributed to 5 girls and 10 boys. Each girl then gave
45 of her share of chocolate bars to the boys. As a result, each boy received 4 more chocolate bars.
- How many chocolate bars did each girl have left?
- Find the total number of chocolate bars each boy had after receiving more chocolate bars from the girls.
(a)
Number of chocolate bars that the girls gave to the boys
= 10 x 4
= 40
Number of chocolate bars that each girl gave to the boys
= 40 ÷ 5
= 8
Number of chocolate bars that each girl had at first = 5 u
Number of chocolate bars that each girl gave away = 4 u
4 u = 8
1 u = 8 ÷ 4 = 2
Number of chocolate bars that each girl left
= 5 u - 4 u
= 1 u
= 2
(b)
Number of chocolate bars that each boy had in the end
= 5 u + 4
= 5 x 2 + 4
= 10 + 4
= 14
Answer(s): (a) 2; (b) 14
