If x = 6 and y = 1, then
4.3xy8 = 4.3618 = 4.361 = 4.36;
However, if we take x = 5 and y = 6, then
4.3xy8 = 4.3568 = 4.356 = 4.36
So, taking value of x as 6 or 5, we get 4.36 in both cases.
That's why Ans is D
4.3xy8 = 4.3618 = 4.361 = 4.36;
However, if we take x = 5 and y = 6, then
4.3xy8 = 4.3568 = 4.356 = 4.36
So, taking value of x as 6 or 5, we get 4.36 in both cases.

x can be 6 or 5 because 550+ also rounds 600 & <650 also rounds to 600.
Hence D.
Hence D.
