Number of apples at first in percent = 100%
Number of starfruits at first in percent
= 100% + 75%
= 175%
StarfruitsApples =
175100 =
74Number of apples sold
= 50% x 4 u
=
50100 x 4 u
= 2 u
Number of more starfruits than apples in the end
= 7 u - 2 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Total number of apples and starfruits at first
= 7 u + 4 u
= 11 u
= 11 x 2
= 22
Answer(s): 22
