A is 25% more than B, and B is 40% less than C. If C is 20% more than D, then A is what percentage less than D?
Answer & explanation
Correct answer: option 2
Let D be 100x
So, C is 20% more than D
C = 100x + 100x × 20% = 120x
B is 40% less than C
B = 120x - 120x × 40% = 72x
A is 25% more than B
A = 72x + 72x × 25% = 90x
Required percentage = \(\frac{(100-72)}{100}\) × 100 = 10%
