Number of lemons at first in percent = 100%
Number of starfruits at first in percent
= 100% + 60%
= 160%

160100 =
85Number of lemons sold
= 40% x 5 u
=
40100 x 5 u
= 2 u
Number of more starfruits than lemons in the end
= 8 u - 3 u
= 5 u
5 u = 20
1 u = 20 ÷ 5 = 4
Total number of lemons and starfruits at first
= 8 u + 5 u
= 13 u
= 13 x 4
= 52
Answer(s): 52
