The ratio of starfruits to mangoes is 2 : 5. If 16 mangoes are added, the ratio of starfruits to mangoes will be 2 : 7. How many more mangoes than starfruits are there in the end?
| |
Starfruits |
Mangoes |
| Before |
2 u |
5 u |
| Change |
|
+ 16 |
| After |
2 u |
7 u |
The number of starfruits at first and in the end remains unchanged.
Number of mangoes added
= 7 u - 5 u
= 2 u
2 u = 16
1 u = 16 ÷ 2 = 8
Number of more mangoes than starfruits in the end
= 7 u - 2 u
= 5 u
= 5 x 8
= 40
Answer(s): 40
