At a fruit stall, there were 779 lemons and persimmons at first.
35 of the lemons and
38 of the persimmons were sold. In the end, there were same number of lemons and persimmons. How many less persimmons than lemons were sold?
| |
Lemons |
Persimmons |
| Before |
5x5 =
25 u |
8x2 =
16 u |
| Change |
- 3x5 =
- 15 u
|
- 3x2 =
- 6 u
|
| After |
2x5 =
10 u |
5x2 =
10 u |
Comparing lemons
and persimmons in the end |
1x10 =
10 u |
1x10 =
10 u |
The number of lemons and persimmons in the end is the same. Make the number of lemons and persimmons in the end the same. LCM of 2, 5 and 1 is 10.
Number of lemons and persimmons in the end
= 25 u + 16 u
= 41 u
41 u = 779
1 u = 779 ÷ 41 = 19
Number of less persimmons than lemons were sold
= 15 u - 6 u
= 9 u
= 9 x 19
= 171
Answer(s): 171
