At a fruit stall, there were 260 mangosteens and apples at first.
14 of the mangosteens and
18 of the apples were sold. In the end, there were same number of mangosteens and apples. How many less apples than mangosteens were sold?
| |
Mangosteens |
Apples |
| Before |
4x7 =
28 u |
8x3 =
24 u |
| Change |
- 1x7 =
- 7 u
|
- 1x3 =
- 3 u
|
| After |
3x7 =
21 u |
7x3 =
21 u |
Comparing mangosteens
and apples in the end |
1x21 =
21 u |
1x21 =
21 u |
The number of mangosteens and apples in the end is the same. Make the number of mangosteens and apples in the end the same. LCM of 3, 7 and 1 is 21.
Number of mangosteens and apples in the end
= 28 u + 24 u
= 52 u
52 u = 260
1 u = 260 ÷ 52 = 5
Number of less apples than mangosteens were sold
= 7 u - 3 u
= 4 u
= 4 x 5
= 20
Answer(s): 20
