If the side of a cube is increased by 100% then by what percentage is the surface area of the cube increased?

 A) 150% B) 200% C) 300% D) 400%

 C) 300%

Surface area of cube = $$\Large 6a^{2}$$

Now if side of cube is increased by 100%

% increase in surface area of cube $$\Large 100 + 100 + \frac{10000}{100}$$%

=(200 + 100)% = 300%

Option (C)is correct.
