Question

A man is twice as old as his son .Twelve years ago,the man was thrice as old as his son .Find their present ages.

Answer 1

Answer:

man's age : 24, son's age : 12

Step-by-step explanation:

let man's age be x

let son's age be y

Equation-1

x=2y

Equation-2

(x-12)=3(y-12)

replace the value of x in equation-2 with 2y, from equation-1 and solve to get the value of y as 12 and the value of x solved by equation-1 will be 24.
