At a fruit stall, there were 690 pomegranates and apples at first.
25 of the pomegranates and
27 of the apples were sold. In the end, there were same number of pomegranates and apples. How many less apples than pomegranates were sold?
| |
Pomegranates |
Apples |
| Before |
5x5 =
25 u |
7x3 =
21 u |
| Change |
- 2x5 =
- 10 u
|
- 2x3 =
- 6 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing pomegranates
and apples in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of pomegranates and apples in the end is the same. Make the number of pomegranates and apples in the end the same. LCM of 3, 5 and 1 is 15.
Number of pomegranates and apples in the end
= 25 u + 21 u
= 46 u
46 u = 690
1 u = 690 ÷ 46 = 15
Number of less apples than pomegranates were sold
= 10 u - 6 u
= 4 u
= 4 x 15
= 60
Answer(s): 60
