Question

5 years hence, father's age will be three times the age of his son. 5 years ago , father was seven times as old as his son. Find the present age.

Answer 1

Answer:

Let the present age of father and son be x and y

Case 1:

After 5 years the age of father will be 3 times the age of the son

(x +5) = 3(y +5)

Case 2:

5 years before the age of the father was 7 times to the age of son

(x-5) = 7(y-5)

now solve by using these two equation
