Number of kiwis that Paul used
=
35 x 80
= 48
Number of kiwis that Paul had left
= 80 - 48
= 32
Number of persimmons that Paul used
=
79 x 162
= 126
Number of persimmons that Paul had left
= 162 - 126
= 36
Fraction of the fruits left that were persimmons
= 1 -
110=
910 Number of kiwis left = 1 u = 32
Number of persimmons left in the end
= 9 u
= 9 x 32
= 288
Number of persimmons that Paul bought
= 288 - 36
= 252
