I have a doubt shouldn't the answer be A? Since order does not matter in multiplication, x*y is 6, so y*x is also 6 right? hence statement A is sufficient in finding xy^2 + yx^2


Your doubt is addressed in the solution aobve:

From \(xy = 6\) it follows that \(x=6\) and \(y=1\) OR \(x=3\) and \(y=2\), thus \(xy^2 + yx^2=42\) or \(xy^2 + yx^2=30\). Two different values, thus this statement is NOT sufficient.
