What is the present age of Surya?

I. Five years ago, Surya age was double that of his son’s age that time.

II. Present age of Surya and his son are in the ratio of 11:6.

III. Five year hence, the respective ratio of Surya’s age and his son’s age become 12:7

Only I and II

Only II and III

Any two of three

All are needed

All the given statements are Insufficient

Three equations and each has two variables.

So from any two we can find.
According to first sentence, (S -5) = 2*(X – 5)

[S is the age of Surya and x is the age of his son] According to second sentence, S:X = 11:6
According to third sentence,

(S + 5)/(X +5) = 12/7

Hence, option 3 is the correct answer.
