Ratio = 39:24:21
Given :
- Mrs. Rifkin had 84 oranges
- 24 of her oranges were rotten
- There were 18 more ripe oranges than unripe oranges
To find :
- the ratio of the number of ripe oranges to the number of rotten oranges to the number of unripe oranges
Solution :
Let the number of riped oranges be x.
Let the number of unriped oranges be y.
Number of rotten oranges = 24 [Given]
- There were 18 more ripe oranges than unripe oranges
Constituting it mathematically,
----> (1)
Total Number of orange = 84
Which includes, riped oranges, unriped oranges and rotten oranges.
•°•
----> (2)
Solve equations 1 and 2 simultaneously by elimination method.
Add equation 2 to equation 1,
x + y = 60
x - y = 18
---------------
2x = 78
Substitute x = 39 in equation 1,
x - y = 18 ----> (1)
39 - y = 18
39 - 18 = y
21 = y
•°• y = 21
•°• Number of riped oranges, x = 39
Number of unriped oranges, y = 21
Number of rotten oranges = 24
Ratio = x : 24 : y
•°•Required ratio = 39 : 24 : 21
