It is important to note that square root of constant is + only ( root 16 is +4). But square root of variable is +/- (root (x+3)^2 is |x+3|)
Chethan92
(x + 3)^2 = 16

x+3 = +4 or -4
x = 1 or -7

(y + 4)^2 = 36

y+4 = +6 or -6
y = 2 or -10

Max of x/y is when x = -7 and y = -10
x/y = 7/10

E is the answer.
