Justin had a total of 687 passion fruits and apples. He sold
15 of the apples and bought another 10 passion fruits. In the end, the number of passion fruits he had was
45 the number of apples. How many more apples than passion fruits did he have at first?

16 u - 10

5x5 = 25 u |
687 |
Change |
+ 10 |
- 1x5 = 5 u |
|
After |
|
4x5 = 20 u |
|
Comparing between passion fruits and apples |
4x4 = 16 u |
5x4 = 20 u |
|
The number of apples in the end is repeated. Make the number of apples in the end the same. LCM of 4 and 5 is 20.
Total number of passion fruits and apples at first
= 16 u - 10 + 25 u
= 41 u - 10
41 u - 10 = 687
41 u = 687 + 10
41 u = 697
1 u = 697 ÷ 41 = 17
Number of more apples than passion fruits at first
= 25 u - (16 u - 10)
= 25 u - 16 u + 10
= 9 u + 10
= 9 x 17 + 10
= 153 + 10
= 163
Answer(s): 163
