(a)
The total number of chocolate bars at first and in the end remains the same.
Total number of chocolate bars in the end
= 3 u + 1 u
= 4 u
4 u = 60
1 u = 60 ÷ 4 = 15
Number of chocolate bars in Basket Y in the end
= 3 u
= 3 x 15
= 45
(b)
Number of chocolate bars in Basket Z in the end
= 1 u
= 15
Answer(s): (a) 45; (b) 15
