At a fruit stall, there were 860 pears and mangosteens at first.
25 of the pears and
16 of the mangosteens were sold. In the end, there were same number of pears and mangosteens. How many less mangosteens than pears were sold?
| |
Pears |
Mangosteens |
| Before |
5x5 =
25 u |
6x3 =
18 u |
| Change |
- 2x5 =
- 10 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing pears
and mangosteens in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of pears and mangosteens in the end is the same. Make the number of pears and mangosteens in the end the same. LCM of 3, 5 and 1 is 15.
Number of pears and mangosteens in the end
= 25 u + 18 u
= 43 u
43 u = 860
1 u = 860 ÷ 43 = 20
Number of less mangosteens than pears were sold
= 10 u - 3 u
= 7 u
= 7 x 20
= 140
Answer(s): 140
