(a)
The total number of chocolate bars at first and in the end remains the same.
Total number of chocolate bars in the end
= 6 u + 1 u
= 7 u
7 u = 70
1 u = 70 ÷ 7 = 10
Number of chocolate bars in Basket K in the end
= 6 u
= 6 x 10
= 60
(b)
Number of chocolate bars in Basket L in the end
= 1 u
= 10
Answer(s): (a) 60; (b) 10
