Answer:

or vertices of the figure

30. Which one of the following inequalities is

always true for positive real numbers x, y?

(a) xy + y

(b) (x + y) = (x + y)

(c) x + y< x2 + y2

(d) 1 + x + y< (1 + x + y)2

(d) 1 + x + y< (1+ x + y)2

Since 1 + x + y>1 and hence the square of

(1 + x + y) is always greater than 1+ x + y.
