To find the value of x + y

Statement 1

$$x + 2 = 5 - y$$

=> $$x + y = 5 - 2$$

=> $$x + y = 3$$

Statement 1 sufficient

Statement 2

$$(x+y)^{2} = 9$$

=> $$x + y = 3$$ or $$x + y = -3$$

Statement 2 not sufficient

Hence option A

St1 yields only one value of (x+y), so sufficient.

In st2, (x+y) is a square term, so (x+y) has two values. So, insufficient.

Ans.(A)

From statement 1:

x+2=5−y

=> x+y=5−2

=> x+y=3

Sufficient

From statement 2:

(x+y)^2=9

=> x+y=3 or x+y=-3
not sufficient

Hence A
