An equal number of jelly beans were distributed to 4 boys and 6 girls. Each boy then gave
23 of her share of jelly beans to the girls. As a result, each girl received 12 more jelly beans.
- How many jelly beans did each boy have left?
- Find the total number of jelly beans each girl had after receiving more jelly beans from the boys.
(a)
Number of jelly beans that the boys gave to the girls
= 6 x 12
= 72
Number of jelly beans that each boy gave to the girls
= 72 ÷ 4
= 18
Number of jelly beans that each boy had at first = 3 u
Number of jelly beans that each boy gave away = 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Number of jelly beans that each boy left
= 3 u - 2 u
= 1 u
= 9
(b)
Number of jelly beans that each girl had in the end
= 3 u + 12
= 3 x 9 + 12
= 27 + 12
= 39
Answer(s): (a) 9; (b) 39
