Number of chikoos that Riordan used
=
45 x 185
= 148
Number of chikoos that Riordan had left
= 185 - 148
= 37
Number of lemons that Riordan used
=
710 x 70
= 49
Number of lemons that Riordan had left
= 70 - 49
= 21
Fraction of the fruits left that were lemons
= 1 -
16=
56 Number of chikoos left = 1 u = 37
Number of lemons left in the end
= 5 u
= 5 x 37
= 185
Number of lemons that Riordan bought
= 185 - 21
= 164
Answer(s): 164
