At a fruit stall, there were 221 starfruits and lemons at first.
35 of the starfruits and
37 of the lemons were sold. In the end, there were same number of starfruits and lemons. How many less lemons than starfruits were sold?
| |
Starfruits |
Lemons |
| Before |
5x2 =
10 u |
7x1 =
7 u |
| Change |
- 3x2 =
- 6 u
|
- 3x1 =
- 3 u
|
| After |
2x2 =
4 u |
4x1 =
4 u |
Comparing starfruits
and lemons in the end |
1x4 =
4 u |
1x4 =
4 u |
The number of starfruits and lemons in the end is the same. Make the number of starfruits and lemons in the end the same. LCM of 2, 4 and 1 is 4.
Number of starfruits and lemons in the end
= 10 u + 7 u
= 17 u
17 u = 221
1 u = 221 ÷ 17 = 13
Number of less lemons than starfruits were sold
= 6 u - 3 u
= 3 u
= 3 x 13
= 39
Answer(s): 39
