At a fruit stall, there were 644 mangoes and persimmons at first.
25 of the mangoes and
27 of the persimmons were sold. In the end, there were same number of mangoes and persimmons. How many less persimmons than mangoes were sold?
| |
Mangoes |
Persimmons |
| Before |
5x5 =
25 u |
7x3 =
21 u |
| Change |
- 2x5 =
- 10 u
|
- 2x3 =
- 6 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing mangoes
and persimmons in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of mangoes and persimmons in the end is the same. Make the number of mangoes and persimmons in the end the same. LCM of 3, 5 and 1 is 15.
Number of mangoes and persimmons in the end
= 25 u + 21 u
= 46 u
46 u = 644
1 u = 644 ÷ 46 = 14
Number of less persimmons than mangoes were sold
= 10 u - 6 u
= 4 u
= 4 x 14
= 56
Answer(s): 56
