Number of lemons at first in percent = 100%
Number of persimmons at first in percent
= 100% + 30%
= 130%

= 80% x 10 u
=
80100 x 10 u
= 8 u
Number of more persimmons than lemons in the end
= 13 u - 2 u
= 11 u
11 u = 77
1 u = 77 ÷ 11 = 7
Total number of lemons and persimmons at first
= 13 u + 10 u
= 23 u
= 23 x 7
= 161
Answer(s): 161
