  1. From the given diagram it is easy to see that a = -1; b = 1 and c = 3
    (Note: a, b, c are integers)

    \ b - a = 1- (-1) = 1 + 1 = 2 and b - c = 1 - 3 = -2 and 2 > -2.

    Hence A.

    OR

    One can even conclude without calculation that b > a (since b is to the right of a), i.e. b - c < 0 i.e. negative.

    \ b - 1 > b - c

    Hence A .

  2. ( x + y)2 = x2 + 2xy + y2

    Hence x2 + 2xy + y2 > x2 + y2

    Since the extra term 2xy on the left hand side of the inequality in positive.
    (
    \ x > 0 and y > 0).

    Hence A.

  3. Even if the student does not know much about polygons he can consider two very common regular polygons namely equilateral triangle whose exterior angle is 1200 and a square whose exterior angle is 900 and arrive at the conclusion that as the number of sides increases (from 3 to 4) the exterior angle decreases from 1200 to 900). Hence the exterior angle of a regular pentagon (five sides) will be more than an exterior angle of a regular hexagon ( 6 sides).

    Hence A.
