At a fruit stall, there were 860 mangosteens and chikoos at first.
25 of the mangosteens and
16 of the chikoos were sold. In the end, there were same number of mangosteens and chikoos. How many less chikoos than mangosteens were sold?

Mangosteens |
Chikoos |
| Before |
5x5 =
25 u |
6x3 =
18 u |
| Change |
- 2x5 =
- 10 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing mangosteens
and chikoos in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of mangosteens and chikoos in the end is the same. Make the number of mangosteens and chikoos in the end the same. LCM of 3, 5 and 1 is 15.
Number of mangosteens and chikoos in the end
= 25 u + 18 u
= 43 u
43 u = 860
1 u = 860 ÷ 43 = 20
Number of less chikoos than mangosteens were sold
= 10 u - 3 u
= 7 u
= 7 x 20
= 140
Answer(s): 140
