At a fruit stall, there were 828 mangosteens and mangoes at first.
25 of the mangosteens and
27 of the mangoes were sold. In the end, there were same number of mangosteens and mangoes. How many more mangosteens than mangoes were sold?
|
Mangosteens |
Mangoes |
Before |
5x5 = 25 u |
7x3 = 21 u |
Change |
- 2x5 = - 10 u
|
- 2x3 = - 6 u
|
After |
3x5 = 15 u |
5x3 = 15 u |
Comparing mangosteens and mangoes in the end |
1x15 = 15 u |
1x15 = 15 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 3, 5 and 1 is 15.
Number of mangosteens and mangoes in the end
= 25 u + 21 u
= 46 u
46 u = 828
1 u = 828 ÷ 46 = 18
Number of more mangosteens than mangoes sold
= 10 u - 6 u
= 4 u
= 4 x 18
= 72
Answer(s): 72
