1.  The sum of the interior angles of a polygon is twice the sum of its exterior angles. How many sides does the polygon have ?
A. 6
B. 4
C. 5
D. 7

Answer: Option A

Explanation:

We know that

Sum of Interior angles of Polygon = 180( n - 2 )

Sum of Exterior angles of Polygon = 360

So 180( n - 2 ) = 2 x 360

Therefore, by solving we get n = 6 sides.
