Other method:

X-19657-33994 = (100000-1).

X-19657 = (100000-1) +33994.

X-19657 = 43994-1.

X = 43993+19657.

X = 63650.

x-19657-33994 = 9999.

x = 9999+19657+33994.

x = 63650.

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.

X=19657+33994=53651.

And then add 9999 means 10000-1.

Then 53651+10000-1=63650 is answer. Its so easy.

9999+33994+19657 = 63650.
