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