Hey guys,

I think the answer for this question should be A. If we have to round up the value to 6 then x>=5.

Why not C? If x=4, rounding up from the last decimal location, 12.1549 becomes 12.155 and again rounding up wouldn’t it lead to 12.16?

Am I wrong somewhere? I saw the answer was A, so could you explain why you thought of A as well?

You cannot round up twice; that is why x has to be equal or greater than 5, meaning that the answer is A

The rounding rules only apply to the next digit.Otherwise you could just keep rounding and rounding: 3.44446 -> 3.4445 -> 3.445 -> 3.45 -> 3.5 -> 4. But we didn’t start out being halfway to 3, so this is wrong.
