Question: The ratio between Karim's age and Rahim's age is 11 : 10. What is the age of Karim as a percentage of Rahim's age?

Solution:
Given that,
The ratio of Karim's age to Rahim's age = 11 : 10

Let, Karim's age = 11x
and Rahim's age = 10x

Now, we find Karim's age as a percentage of Rahim's age,

∴ Percentage = (Karim’s age/Rahim’s age​) × 100
= (11x/10x) × 100
= 110

So, Karim's age is 110% of Rahim's age.
