Aptitude Problems on Ages Concepts and Formulas

Points to remember:

1) t years ago the age of A was n1 times the age of B, and at present A's age is n2 times that of B, then;
A's present age = Problem on ages Sign Apti Problem on ages 1Problem on ages Sign 2 n2∗t years
And, B's present age = Problem on ages Sign Apti Problem on ages 2Problem on ages Sign 2 t years

2) The present age of A is n1 times the present age of B. After t years, age of A becomes n2 times the age of B, then;
A's present age = Problem on ages Sign Apti Problem on ages 3Problem on ages Sign 2 n2 ∗ t years
And, B's present age = Problem on ages Sign Apti Problem on ages 4Problem on ages Sign 2 t years

3) t1 years ago, the age of A was X times the age of B and after t2 years age of A becomes Y times the age of B, then;
A's present age = Apti Problem on ages 5+ t1 years

And B's present age = Apti Problem on ages 6years

4) The sum of present ages of A and B is X years, t years ago, the age of A was Y times the age of B, then;
Present age of A = Apti Problem on ages 7Years

And, the present age of B = Apti Problem on ages 8Years

5) The sum of present ages of A and B is X years, t years after, the age of A becomes Y times the age of B, then;
A's present age = Apti Problem on ages 9Years

And B's present age= Apti Problem on ages 10Years

6) The ratio of the present ages of A and B is p: q and after t years, it becomes r: s, then;
A's present age = Apti Problem on ages 11Years

And, B's present age = Apti Problem on ages 12Years
