At a fruit stall, there were 459 mangosteens and apples at first.
35 of the mangosteens and
18 of the apples were sold. In the end, there were same number of mangosteens and apples. How many more mangosteens than apples were sold?
| |
Mangosteens |
Apples |
| Before |
5x7 =
35 u |
8x2 =
16 u |
| Change |
- 3x7 =
- 21 u
|
- 1x2 =
- 2 u
|
| After |
2x7 =
14 u |
7x2 =
14 u |
Comparing mangosteens
and apples in the end |
1x14 =
14 u |
1x14 =
14 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 2, 7 and 1 is 14.
Number of mangosteens and apples in the end
= 35 u + 16 u
= 51 u
51 u = 459
1 u = 459 ÷ 51 = 9
Number of more mangosteens than apples sold
= 21 u - 2 u
= 19 u
= 19 x 9
= 171
Answer(s): 171
