A is 20% more than B, B is 25% more than C, C is 50% less than D and D is 10% more than E. Which of the following is true?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. A is 17.5% less than E.
Let E = 100
D is 10% more than E
⇒ D = 100 + 10% of 100 = 110
C is 50% less than D
⇒ C = 110 - 50% of 110 = 55
B is 25% more than C
⇒ B = 55 + 25% of 55 = 68.75
A is 20% more than B
⇒ A = 68.75 + 20% of 68.75 = 82.5
Check option 1:
(100 - 82.5) / 100 × 100 = 17.5%
⇒ A is 17.5% less than E
