Question

3 years ago a father was 3 times as old as his son in 5 years time he will be twice as old as his son in, what will be the sum of their years in four years time ​

Answer 1

46 because if the age of the son was 8 then the father was 24 and if we add 8 (because that’s how many years passed) we get 16 and 32 which fit the criteria so if we take off 1 year on each (because only 7 years pass instead of 8) we can add them together and get 46
