At a fruit stall, there were 468 mangosteens and persimmons at first.
14 of the mangosteens and
18 of the persimmons were sold. In the end, there were same number of mangosteens and persimmons. How many less persimmons than mangosteens were sold?
| |
Mangosteens |
Persimmons |
| Before |
4x7 =
28 u |
8x3 =
24 u |
| Change |
- 1x7 =
- 7 u
|
- 1x3 =
- 3 u
|
| After |
3x7 =
21 u |
7x3 =
21 u |
Comparing mangosteens
and persimmons in the end |
1x21 =
21 u |
1x21 =
21 u |
The number of mangosteens and persimmons in the end is the same. Make the number of mangosteens and persimmons in the end the same. LCM of 3, 7 and 1 is 21.
Number of mangosteens and persimmons in the end
= 28 u + 24 u
= 52 u
52 u = 468
1 u = 468 ÷ 52 = 9
Number of less persimmons than mangosteens were sold
= 7 u - 3 u
= 4 u
= 4 x 9
= 36
Answer(s): 36
