Question
Select all the correct answersThe ratio of the present ages of A and B is 8 : 9. After 9 years, this will become 19 : 21. C is 3 years younger to B. What is the present age (in years) of C?Options5154948
Solution
Let's solve this step by step:
-
The present age ratio of A and B is 8:9. Let's assume the present age of A is 8x and the present age of B is 9x.
-
After 9 years, the ratio of their ages will be 19:21. So, we can write the equation as (8x + 9) / (9x + 9) = 19/21.
-
Solving this equation, we get x = 3.
-
So, the present age of B is 9x = 9*3 = 27 years.
-
C is 3 years younger than B. So, the present age of C is 27 - 3 = 24 years.
So, the correct answer is 24 years.
