At a fruit stall, there were 380 pomegranates and apples at first.
14 of the pomegranates and
16 of the apples were sold. In the end, there were same number of pomegranates and apples. How many more pomegranates than apples were sold?
| |
Pomegranates |
Apples |
| Before |
4x5 =
20 u |
6x3 =
18 u |
| Change |
- 1x5 =
- 5 u
|
- 1x3 =
- 3 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
= 20 u + 18 u
= 38 u
38 u = 380
1 u = 380 ÷ 38 = 10
Number of more pomegranates than apples sold
= 5 u - 3 u
= 2 u
= 2 x 10
= 20
Answer(s): 20
