Number of lemons at first in percent = 100%
Number of starfruits at first in percent
= 100% + 40%
= 140%

75Number of lemons sold
= 20% x 5 u
=
20100 x 5 u
= 1 u
Number of more starfruits than lemons in the end
= 7 u - 4 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Total number of lemons and starfruits at first
= 7 u + 5 u
= 12 u
= 12 x 4
= 48
Answer(s): 48
