Fraction of the banana wafers left
= 1 -
15=
45 The number of banana and apple wafers in the end is the same.
Total number of wafers at first
= 5 u + 4 u + 23
= 9 u + 23
9 u + 23 = 50
9 u = 50 - 23
9 u = 27
1 u = 27 ÷ 9 = 3
Number of apple wafers at first
= 4 u + 23
= 4 x 3 + 23
= 12 + 23
= 35
Answer(s): 35
