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

= 50% x 10 u
=
50100 x 10 u
= 5 u
Number of more apples than starfruits in the end
= 19 u - 5 u
= 14 u
14 u = 84
1 u = 84 ÷ 14 = 6
Total number of starfruits and apples at first
= 19 u + 10 u
= 29 u
= 29 x 6
= 174
