At a fruit stall, there were 1040 apples and mangosteens at first.
14 of the apples and
18 of the mangosteens were sold. In the end, there were same number of apples and mangosteens. How many more apples than mangosteens were sold?
| |
Apples |
Mangosteens |
| Before |
4x7 =
28 u |
8x3 =
24 u |
| Change |
- 1x7 =
- 7 u
|
- 1x3 =
- 3 u
|
| After |
3x7 =
21 u |
7x3 =
21 u |
Comparing apples
and mangosteens in the end |
1x21 =
21 u |
1x21 =
21 u |
The number of apples and mangosteens in the end is the same. Make the number of apples and mangosteens in the end the same. LCM of 3, 7 and 1 is 21.
Number of apples and mangosteens in the end
= 28 u + 24 u
= 52 u
52 u = 1040
1 u = 1040 ÷ 52 = 20
Number of more apples than mangosteens sold
= 7 u - 3 u
= 4 u
= 4 x 20
= 80
Answer(s): 80
