At a fruit stall, there were 154 mangosteens and mangoes at first.
35 of the mangosteens and
17 of the mangoes were sold. In the end, there were same number of mangosteens and mangoes. How many less mangoes than mangosteens were sold?
| |
Mangosteens |
Mangoes |
| Before |
5x3 =
15 u |
7x1 =
7 u |
| Change |
- 3x3 =
- 9 u
|
- 1x1 =
- 1 u
|
| After |
2x3 =
6 u |
6x1 =
6 u |
Comparing mangosteens
and mangoes in the end |
1x6 =
6 u |
1x6 =
6 u |
The number of mangosteens and mangoes in the end is the same. Make the number of mangosteens and mangoes in the end the same. LCM of 2, 6 and 1 is 6.
Number of mangosteens and mangoes in the end
= 15 u + 7 u
= 22 u
22 u = 154
1 u = 154 ÷ 22 = 7
Number of less mangoes than mangosteens were sold
= 9 u - 1 u
= 8 u
= 8 x 7
= 56
Answer(s): 56
