At a fruit stall, there were 559 lemons and mangosteens at first.
25 of the lemons and
16 of the mangosteens were sold. In the end, there were same number of lemons and mangosteens. How many less mangosteens than lemons were sold?
|
Lemons |
Mangosteens |
Before |
5x5 = 25 u |
6x3 = 18 u |
Change |
- 2x5 = - 10 u
|
- 1x3 = - 3 u
|
After |
3x5 = 15 u |
5x3 = 15 u |
Comparing lemons and mangosteens in the end |
1x15 = 15 u |
1x15 = 15 u |
The number of lemons and mangosteens in the end is the same. Make the number of lemons and mangosteens in the end the same. LCM of 3, 5 and 1 is 15.
Number of lemons and mangosteens in the end
= 25 u + 18 u
= 43 u
43 u = 559
1 u = 559 ÷ 43 = 13
Number of less mangosteens than lemons were sold
= 10 u - 3 u
= 7 u
= 7 x 13
= 91
Answer(s): 91
