At a fruit stall, there were 407 lemons and apples at first.
35 of the lemons and
16 of the apples were sold. In the end, there were same number of lemons and apples. How many less apples than lemons were sold?
| |
Lemons |
Apples |
| Before |
5x5 =
25 u |
6x2 =
12 u |
| Change |
- 3x5 =
- 15 u
|
- 1x2 =
- 2 u
|
| After |
2x5 =
10 u |
5x2 =
10 u |
Comparing lemons
and apples in the end |
1x10 =
10 u |
1x10 =
10 u |
The number of lemons and apples in the end is the same. Make the number of lemons and apples in the end the same. LCM of 2, 5 and 1 is 10.
Number of lemons and apples in the end
= 25 u + 12 u
= 37 u
37 u = 407
1 u = 407 ÷ 37 = 11
Number of less apples than lemons were sold
= 15 u - 2 u
= 13 u
= 13 x 11
= 143
Answer(s): 143
