An equal number of chocolate bars were distributed to 4 girls and 10 boys. Each girl then gave
23 of her share of chocolate bars to the boys. As a result, each boy received 12 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 12
= 120
Number of chocolate bars that each girl gave to the boys
= 120 ÷ 4
= 30
Number of chocolate bars that each girl had at first = 3 u
Number of chocolate bars that each girl gave away = 2 u
2 u = 30
1 u = 30 ÷ 2 = 15
Number of chocolate bars that each girl left
= 3 u - 2 u
= 1 u
= 15
(b)
Number of chocolate bars that each boy had in the end
= 3 u + 12
= 3 x 15 + 12
= 45 + 12
= 57
Answer(s): (a) 15; (b) 57
