The ratio of guavas to passion fruits is 3 : 7. If 25 passion fruits are added, the ratio of guavas to passion fruits will be 1 : 4. How many passion fruits are there?
|
Guavas |
Passion Fruits |
Before |
3x1 = 3 u |
7x1 = 7 u |
Change |
|
+ 25 |
After |
1x3 = 3 u |
4x3 = 12 u |
The number of guavas at first and in the end remains unchanged. Make the number of guavas at first and in the end the same. LCM of 3 and 1 is 3.
Number of passion fruits added
= 12 u - 7 u
= 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Number of passion fruits
= 7 u
= 7 x 5
= 35
Answer(s): 35
