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

1710Number of persimmons sold
= 10% x 10 u
=
10100 x 10 u
= 1 u
Number of more pears than persimmons in the end
= 17 u - 9 u
= 8 u
8 u = 88
1 u = 88 ÷ 8 = 11
Total number of persimmons and pears at first
= 17 u + 10 u
= 27 u
= 27 x 11
= 297
