Number of apples at first in percent = 100%
Number of oranges at first in percent
= 100% + 90%
= 190%

= 30% x 10 u
=
30100 x 10 u
= 3 u
Number of more oranges than apples in the end
= 19 u - 7 u
= 12 u
12 u = 24
1 u = 24 ÷ 12 = 2
Total number of apples and oranges at first
= 19 u + 10 u
= 29 u
= 29 x 2
= 58
