An equal number of jelly beans were distributed to 7 boys and 9 girls. Each boy then gave
34 of her share of jelly beans to the girls. As a result, each girl received 7 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
= 9 x 7
= 63
Number of jelly beans that each boy gave to the girls
= 63 ÷ 7
= 9
Number of jelly beans that each boy had at first = 4 u
Number of jelly beans that each boy gave away = 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Number of jelly beans that each boy left
= 4 u - 3 u
= 1 u
= 3
(b)
Number of jelly beans that each girl had in the end
= 4 u + 7
= 4 x 3 + 7
= 12 + 7
= 19
Answer(s): (a) 3; (b) 19
