Question : P is 20% more than Q. Q is how much percentage less than P?
Option 1: 14.28%
Option 2: 33.33%
Option 3: 16.66%
Option 4: 8.33%
Correct Answer: 16.66%
Solution :
Percentage Decrease = $\frac{\text{Original Value – New Value}}{ \text{Original Value}}$ × 100
Let's say $Q = 100$ then $P= 120$
The original value is P, and the new value is Q. So,
Percentage Decrease = $\frac{\text{Original Value – New Value}}{\text{Original Value}}$ × 100
= $\frac{120 - 100}{120}$ × 100
= 16.66%
Hence, the correct answer is 16.66%.
