Number of lemons at first in percent = 100%
Number of pears at first in percent
= 100% + 90%
= 190%

1910Number of lemons sold
= 70% x 10 u
=
70100 x 10 u
= 7 u
Number of more pears than lemons in the end
= 19 u - 3 u
= 16 u
16 u = 192
1 u = 192 ÷ 16 = 12
Total number of lemons and pears at first
= 19 u + 10 u
= 29 u
= 29 x 12
= 348
