The ratio of pears to mangosteens is 2 : 5. If 44 mangosteens are added, the ratio of pears to mangosteens will be 2 : 9. How many less pears than mangosteens are there in the end?
| |
Pears |
Mangosteens |
| Before |
2 u |
5 u |
| Change |
|
+ 44 |
| After |
2 u |
9 u |
The number of pears at first and in the end remains unchanged.
Number of mangosteens added
= 9 u - 5 u
= 4 u
4 u = 44
1 u = 44 ÷ 4 = 11
Number of less pears than mangosteens in the end
= 9 u - 2 u
= 7 u
= 7 x 11
= 77
Answer(s): 77
