What is the age of Teja?
A: Four years ago, Raju was as old as Teja is at present.
B: Sita’s present age is two times of Raju’s present age.
C: The average age of Teja and Sita is 19 years.
Answer with explanationAnswer: Option C
From the given statements A, B & C
Let the present age of Teja = P
Raju present age = P + 4
Sita’s present age = 2(P + 4)
Average of ages of Sita & Teja = 19
=> (2P + 8 + P)/2 = 19
= 3P + 8 = 38
=> P = 30/3 = 10
Hence, the present age of Teja = P = 10 yrs.
Therefore, by using all the three statements A, B & C we can find the age of Teja.
