In the picture given below, there are certain number of points in the interior and the exterior of the circle:
What is the difference between the number of points in the interior of the circle and the number of points in the exterior of the circle?

• A.
  1
• B.
  8
• C.
  4
• D.
  3

Answer 1

The correct option is C

4
All the points within the boundary of the circle are said to be in the interior of the circle.
$\therefore$ In the given figue, the number of points in the interior of the circle = 6

All the points which are outside the boundary of the circle are said to be in the exterior of the circle.
$\therefore$ In the given figue, the number of points in the interior of the circle = 2

$\therefore$ The required difference = 6 - 2 = 4
