The ratio of mangosteens to starfruits is 2 : 7. If 44 starfruits are added, the ratio of mangosteens to starfruits will be 2 : 11. How many less mangosteens than starfruits are there in the end?
| |
Mangosteens |
Starfruits |
| Before |
2 u |
7 u |
| Change |
|
+ 44 |
| After |
2 u |
11 u |
The number of mangosteens at first and in the end remains unchanged.
Number of starfruits added
= 11 u - 7 u
= 4 u
4 u = 44
1 u = 44 ÷ 4 = 11
Number of less mangosteens than starfruits in the end
= 11 u - 2 u
= 9 u
= 9 x 11
= 99
Answer(s): 99
