At a fruit stall, there were 516 persimmons and oranges at first.
25 of the persimmons and
16 of the oranges were sold. In the end, there were same number of persimmons and oranges. How many more persimmons than oranges were sold?
| |
Persimmons |
Oranges |
| Before |
5x5 =
25 u |
6x3 =
18 u |
| Change |
- 2x5 =
- 10 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing persimmons
and oranges in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of persimmons and oranges in the end is the same. Make the number of persimmons and oranges in the end the same. LCM of 3, 5 and 1 is 15.
Number of persimmons and oranges in the end
= 25 u + 18 u
= 43 u
43 u = 516
1 u = 516 ÷ 43 = 12
Number of more persimmons than oranges sold
= 10 u - 3 u
= 7 u
= 7 x 12
= 84
Answer(s): 84
