Number of oranges at first in percent = 100%
Number of starfruits at first in percent
= 100% + 80%
= 180%

95Number of oranges sold
= 20% x 5 u
=
20100 x 5 u
= 1 u
Number of more starfruits than oranges in the end
= 9 u - 4 u
= 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Total number of oranges and starfruits at first
= 9 u + 5 u
= 14 u
= 14 x 5
= 70
