A) Any two statements are sufficient to give answer | B) Only C is sufficient |
C) All of three statements are necessary to give answer | D) Even using all the three statements answer cannot be found |
Answer: C) All of three statements are necessary to give answer
Explanation:
Explanation:
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.
