(a)
The total number of jelly beans at first and in the end remains the same.
Total number of jelly beans in the end
= 3 u + 1 u
= 4 u
4 u = 76
1 u = 76 ÷ 4 = 19
Number of jelly beans in Basket Q in the end
= 3 u
= 3 x 19
= 57
(b)
Number of jelly beans in Basket R in the end
= 1 u
= 19
Answer(s): (a) 57; (b) 19
