In the given figure, shaded area is less than the un-shaded area by
Correct answer: C. 25%
- A. 10%
- B. 20%
- C. 25%
- D. 30%
Explanation
This is the correct answer. The shaded area is exactly 25% less than the un-shaded area.if we count the full figure (it's a 2×4 grid).There are 3 shaded and 5 unshaded squares → difference = 5 − 3 = 2 squares.Out of the 8 total squares, the difference is 2/8×100=25%So in this case, the shaded area is 25% less than the un-shaded area, making Option C the correct choice. Options A and B are incorrect as the percentage difference is greater than 10% and 20% respectively. Option D is incorrect because the difference is not as large as 30%.
