This is so simple to add numbers, there are small numbers. But my solution can help to solve big numbers also.

We know that 17*2 = 34, So 0.017+.0.617 = 0.634,

Now 40+17 = 57, so 0.6340+0.0017 = 0.6357.

6*2=12 and 12+17=29,[where 17 is the last two digits of 617 ]

So, the answers is 629.6357.

If you want to add of all you will get 629.6257.

So I think option D will be correct answer.

@Bimal, you are missing one that's carried from (7+7+1 = 15).
