If Riya's age is four times the age of Siya and if Riya's age is 24 yrs , find the age difference between Riya and Siya ?

A 2 yrs

B 12 yrs

C 18 yrs

D 6 yrs

Solution

Correct Answer: Option C

Let Siya's age = x

Then Riya's age = 4x

But given Riya's age = 24

=> 4x = 24 => x = 6

Hence Siya's age = 6 yrs

=> The age difference = 24 - 6 = 18 yrs.
