The ratio of mangoes to starfruits is 3 : 4. If 24 starfruits are added, the ratio of mangoes to starfruits will be 3 : 8. How many less mangoes than starfruits are there in the end?
| |
Mangoes |
Starfruits |
| Before |
3 u |
4 u |
| Change |
|
+ 24 |
| After |
3 u |
8 u |
The number of mangoes at first and in the end remains unchanged.
Number of starfruits added
= 8 u - 4 u
= 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Number of less mangoes than starfruits in the end
= 8 u - 3 u
= 5 u
= 5 x 6
= 30
Answer(s): 30
