My present age is 1287 times the reciprocal of my age 6 years back. What is my present age?

Let the present age be x. Then $x = 1287/{x - 6}$. At this stage a better option is that you try putting the given answers into this expression one by one. The other option is to simplify this expression into a quadratic equation $x × (x - 6)$ = 1287. This can now be solved to give x = 39 years.
