She asks him: "Is your number larger than 50?"
Vijay answers, but lies.
Upon this, Lata asks: "Is your number a multiple of 4?"
Vijay answers, but lies again.
Then Lata asks: "Is your number a square?"
Vijay answers truthfully.
Upon this, Lata says: "I know your number if you tell me whether the first digit is a 3."
Vijay answers, but now we don't know whether he lies or speaks the truth.

Thereupon, Lata says at which number she thinks Vijay lives, but (of course) she is wrong.

What is Vijay's real house-number?
