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 ?
Answer: D
Let Siya's age = \(x\)
Then Riya's age = \(4x\)
But given Riya's age = 24
\(\Rightarrow 4x=24\)
\(\Rightarrow x=6\)
Hence Siya's age = 6 yrs
\(\Rightarrow\) The age difference = 24 - 6 = 18 yrs.
