At a fruit stall, there were 390 starfruits and passion fruits at first.
35 of the starfruits and
27 of the passion fruits were sold. In the end, there were same number of starfruits and passion fruits. How many less passion fruits than starfruits were sold?
|
Starfruits |
Passion Fruits |
Before |
5x5 = 25 u |
7x2 = 14 u |
Change |
- 3x5 = - 15 u
|
- 2x2 = - 4 u
|
After |
2x5 = 10 u |
5x2 = 10 u |
Comparing starfruits and passion fruits in the end |
1x10 = 10 u |
1x10 = 10 u |
The number of starfruits and passion fruits in the end is the same. Make the number of starfruits and passion fruits in the end the same. LCM of 2, 5 and 1 is 10.
Number of starfruits and passion fruits in the end
= 25 u + 14 u
= 39 u
39 u = 390
1 u = 390 ÷ 39 = 10
Number of less passion fruits than starfruits were sold
= 15 u - 4 u
= 11 u
= 11 x 10
= 110
Answer(s): 110
