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

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

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

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

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

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