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

1710Number of mangosteens sold
= 40% x 10 u
=
40100 x 10 u
= 4 u
Number of more persimmons than mangosteens in the end
= 17 u - 6 u
= 11 u
11 u = 110
1 u = 110 ÷ 11 = 10
Total number of mangosteens and persimmons at first
= 17 u + 10 u
= 27 u
= 27 x 10
= 270
Answer(s): 270
