At a fruit stall, there were 255 mangoes and persimmons at first.
35 of the mangoes and
37 of the persimmons were sold. In the end, there were same number of mangoes and persimmons. How many more mangoes than persimmons were sold?
| |
Mangoes |
Persimmons |
| Before |
5x2 =
10 u |
7x1 =
7 u |
| Change |
- 3x2 =
- 6 u
|
- 3x1 =
- 3 u
|
| After |
2x2 =
4 u |
4x1 =
4 u |
Comparing mangoes
and persimmons in the end |
1x4 =
4 u |
1x4 =
4 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 2, 4 and 1 is 4.
Number of mangoes and persimmons in the end
= 10 u + 7 u
= 17 u
17 u = 255
1 u = 255 ÷ 17 = 15
Number of more mangoes than persimmons sold
= 6 u - 3 u
= 3 u
= 3 x 15
= 45
Answer(s): 45
