 Latha said: (Jan 2, 2014) x-19657-33994 = 9999. x = 9999+19657+33994. x = 63650.

 Sanjeev Varma said: (May 24, 2014) x-19657-33994 = 9999. x-19657-3393-1 = 10000-1. x-19657-3393 = 10000. Now look at the options if we find the last 3 digits we will find the answer and at the same time we can save time. So, In this case we are adding so take last 3 digits. 000+993+657. 1650 option a is right.

 Nishant Kumar said: (Jul 18, 2015) X=19657+33994=53651. And then add 9999 means 10000-1. Then 53651+10000-1=63650 is answer. Its so easy.
