Person A was born on January 15, 1948

Person B was born on January 15, 1962

If both were alive now, in what year was person A twice as old as person B?

let in x years from 1962 A will be twice of B

age of B = x

age of A = x + 14

=> x+14 = 2x

=> x = 14

in 14 january 1976 A will be twice as old as B
