Ok . I would go with option D .
Cause they have just mentioned dat x and y are decimals.
We do not know whether they are positv negative . Either which way let us take a few cases .
Case 1 :
If x = 0.007 and y = 0.0001
-》 x + y = 0.0071
X + y rounded to the hundredth placs it gives 0.007 which is x
Hence x = 0.007
You can choose option (C)
Case 2 :
X = 0.006 and y = 0.0001
X+y = 0.0061
Rounded off gives 0.006 which is = x
Hence you could choose option (B)
With jus two cases we get varying answers.
So we need more info to know what precise values of x and y are we allowed to take .
Hence d qns would be option (D)
Hope dis helped.
Kudos plz if it did :D
