Warren bought some lemons and passion fruits in the ratio of 1 : 4 . After buying another 115 fruits each, the ratio becomes 8 : 9. Find the number of lemons and passion fruits he has now.

| Before |
1x1 =
1 u |
4x1 =
4 u |
3x1 =
3 u |
| Change |
+ 115 |
+ 115 |

| After |
8x3 =
24 u |
9x3 =
27 u |
1x3 =
3 u |
Since the same number of fruits bought for each type of fruits is the same, the difference in the number of lemons and passion fruits at first and in the end remains unchanged.
Make the difference in the number of lemons and passion fruits the same. LCM of 3 and 1 is 3.
Increase in the number of lemons
= 24 u - 1 u
= 23 u
23 u = 115
1 u = 115 ÷ 23 = 5
Number of passion fruits and lemons that $(Fred) has now
= 24 u + 27 u
= 51 u
= 51 x 5
= 255
Answer(s): 255
