Number of pears at first in percent = 100%
Number of apples at first in percent
= 100% + 90%
= 190%
ApplesPears =
190100 =
1910Number of pears sold
= 30% x 10 u
=
30100 x 10 u
= 3 u
Number of more apples than pears in the end
= 19 u - 7 u
= 12 u
12 u = 108
1 u = 108 ÷ 12 = 9
Total number of pears and apples at first
= 19 u + 10 u
= 29 u
= 29 x 9
= 261
Answer(s): 261
