The ratio of mangoes to passion fruits is 3 : 8. If 30 passion fruits are added, the ratio of mangoes to passion fruits will be 2 : 7. How many mangoes are there?
|
Mangoes |
Passion Fruits |
Before |
3x2 = 6 u |
8x2 = 16 u |
Change |
|
+ 30 |
After |
2x3 = 6 u |
7x3 = 21 u |
The number of mangoes at first and in the end remains unchanged. Make the number of mangoes at first and in the end the same. LCM of 3 and 2 is 6.
Number of passion fruits added
= 21 u - 16 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Number of mangoes
= 6 u
= 6 x 6
= 36
Answer(s): 36
