At a fruit stall, there were 468 mangoes and starfruits at first.
35 of the mangoes and
27 of the starfruits were sold. In the end, there were same number of mangoes and starfruits. How many less starfruits than mangoes were sold?
|
Mangoes |
Starfruits |
Before |
5x5 = 25 u |
7x2 = 14 u |
Change |
- 3x5 = - 15 u
|
- 2x2 = - 4 u
|
After |
2x5 = 10 u |
5x2 = 10 u |
Comparing mangoes and starfruits in the end |
1x10 = 10 u |
1x10 = 10 u |
The number of mangoes and starfruits in the end is the same. Make the number of mangoes and starfruits in the end the same. LCM of 2, 5 and 1 is 10.
Number of mangoes and starfruits in the end
= 25 u + 14 u
= 39 u
39 u = 468
1 u = 468 ÷ 39 = 12
Number of less starfruits than mangoes were sold
= 15 u - 4 u
= 11 u
= 11 x 12
= 132
Answer(s): 132
