Question

If Ritu were younger by 5 years than what she really is, then the square of her age would have been 11 more than five times her present age. What is her present age?

Answer 1

Let Present age of Ritu = x years 

Given that 

If Ritu were younger by 5 year than what she really is, then the square of her age would have been 11 more than five times her present age. 

(Ritu's age - 5)² = 5 x Present Age + 11

∴  x = 1, x = 14 

But x = 1 is not possible as Ritu's age 5 years ago cannot be negative 

Thus, x = 14

∴ Ritu's Present Age = 14 years
