At a fruit stall, there were 832 mangosteens and oranges at first.
14 of the mangosteens and
18 of the oranges were sold. In the end, there were same number of mangosteens and oranges. How many more mangosteens than oranges were sold?
| |
Mangosteens |
Oranges |
| Before |
4x7 =
28 u |
8x3 =
24 u |
| Change |
- 1x7 =
- 7 u
|
- 1x3 =
- 3 u
|
| After |
3x7 =
21 u |
7x3 =
21 u |
Comparing mangosteens
and oranges in the end |
1x21 =
21 u |
1x21 =
21 u |
The number of mangosteens and oranges in the end is the same. Make the number of mangosteens and oranges in the end the same. LCM of 3, 7 and 1 is 21.
Number of mangosteens and oranges in the end
= 28 u + 24 u
= 52 u
52 u = 832
1 u = 832 ÷ 52 = 16
Number of more mangosteens than oranges sold
= 7 u - 3 u
= 4 u
= 4 x 16
= 64
Answer(s): 64
