| After |
5x4 =

7x4 =
28 u |
Since the same number of fruits bought for each type of fruits is the same, the difference in the number of passion fruits and guavas at first and in the end remains unchanged.
Make the difference in the number of passion fruits and guavas the same. LCM of 4 and 7 is 28.
Increase in the number of passion fruits
= 20 u - 7 u
= 13 u
13 u = 52
1 u = 52 ÷ 13 = 4
Number of guavas and passion fruits that Oliver had at first
= 7 u + 35 u
= 42 u
= 42 x 4
= 168
Answer(s): 168
