Question

four years ago my father's age was 4 times that of my age. at present, the sum of my father's age and that of mine is 53 years. what is my father's present age?

Answer 1

Let your age four years ago be x
then four years ago your father's age=4x
after four years your age=x+4
after four years your father's age=4x+4
Equation is
53=(x+4)+(4x+4)
53=5x+8
x=9

Answer 2

Answer: My age = 13; Father's age = 40

Step-by-step explanation:

Four year ago,

my age=x

Father's age= 4x

present

my=x+4

father's age=4x+4

According to the question

x+4+4x+4=53

5x+8=53

x=9

present age= x+4=9+4=13

Father's age = 4(9)+4=40
