At a fruit stall, there were 340 lemons and starfruits at first.
25 of the lemons and
17 of the starfruits were sold. In the end, there were same number of lemons and starfruits. How many more lemons than starfruits were sold?
| |
Lemons |
Starfruits |
| Before |
5x2 =
10 u |
7x1 =
7 u |
| Change |
- 2x2 =
- 4 u
|
- 1x1 =
- 1 u
|
| After |
3x2 =
6 u |
6x1 =
6 u |
Comparing lemons
and starfruits in the end |
1x6 =
6 u |
1x6 =
6 u |
The number of lemons and starfruits in the end is the same. Make the number of lemons and starfruits in the end the same. LCM of 3, 6 and 1 is 6.
Number of lemons and starfruits in the end
= 10 u + 7 u
= 17 u
17 u = 340
1 u = 340 ÷ 17 = 20
Number of more lemons than starfruits sold
= 4 u - 1 u
= 3 u
= 3 x 20
= 60
Answer(s): 60
