At a fruit stall, there were 228 oranges and mangosteens at first.
14 of the oranges and
16 of the mangosteens were sold. In the end, there were same number of oranges and mangosteens. How many more oranges than mangosteens were sold?
| |
Oranges |
Mangosteens |
| Before |
4x5 =
20 u |
6x3 =
18 u |
| Change |
- 1x5 =
- 5 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing oranges
and mangosteens in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of oranges and mangosteens in the end is the same. Make the number of oranges and mangosteens in the end the same. LCM of 3, 5 and 1 is 15.
Number of oranges and mangosteens in the end
= 20 u + 18 u
= 38 u
38 u = 228
1 u = 228 ÷ 38 = 6
Number of more oranges than mangosteens sold
= 5 u - 3 u
= 2 u
= 2 x 6
= 12
Answer(s): 12
