A is 25% more than B and B is 30% less than C. If C is 20% more than D, then by what percentage is A more than D?
Formula Used:
A = B + 25% of B
B = C - 30% of C
C = D + 20% of D
Calculation:
Let D = 100
⇒ C = 100 + 20% of 100
⇒ C = 100 + 20
⇒ C = 120
⇒ B = 120 - 30% of 120
⇒ B = 120 - 36
⇒ B = 84
⇒ A = 84 + 25% of 84
⇒ A = 84 + 21
⇒ A = 105
Percentage by which A is more than D:
⇒ (A - D)/(D) × 100
⇒ (105 - 100)/(100) × 100
⇒ (5)/(100) × 100
⇒ 5%
∴ The correct answer is option (1).
