Solution

The correct option is D
if x ≤ y

I. $x^{2}$ - 365 = 364
Or $x^{2}$ = 364 + 365 = 729
Or x = $\pm$ 27
II. $y - \sqrt{324} = \sqrt{81}$
Or y - 18 = 9
Or y = 27
So x $\leq$ y is the answer.

I. x2−365=364 II. y−√324=√81

The correct option is D if x ≤ y I. x2 - 365 = 364 Or x2 = 364 + 365 = 729 Or x = ± 27 II. y−√324=√81 Or y - 18 = 9 Or y = 27 So x ≤ y is the answer.
