Question

Father said to his daughter that when, I was of your age you were of age 4 and when ypu will be of my age I will be 79 years old. whose age how much

Answer 1

The question may seem tricky but after seeing the solution you might be surprised.

First of all, let us assume that the present age of father & daughter is x and y. Now  acc. to question, 

Father                  Daughter

  x                                y
 
  y                                4

 79                              x

Since these are the ages at the same time interval so the age difference after every interval must be the same.

i.e. x - y = y - 4 = 79 - x.

or,  x - y = y - 4 ----------- (i)

or, y - 4 = 79 - x ----------- (ii)

Solving these two equations you'll get x = 54 i.e. present age of father and y = 29 i.e. present age of daughter.
