Number of oranges at first in percent = 100%
Number of persimmons at first in percent
= 100% + 70%
= 170%

1710Number of oranges sold
= 80% x 10 u
=
80100 x 10 u
= 8 u
Number of more persimmons than oranges in the end
= 17 u - 2 u
= 15 u
15 u = 105
1 u = 105 ÷ 15 = 7
Total number of oranges and persimmons at first
= 17 u + 10 u
= 27 u
= 27 x 7
= 189
