There are three numbers, P, Q, and R. 30% of P is equal to 15% of Q. 20% of Q is equal to 10% of R. By what percentage is R more than P?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 300%.
(30/100)P = (15/100)Q
⇒ Q = 2P
Also, (20/100)Q = (10/100)R
⇒ R = 2Q = 4P
So, R - P = 4P - P = 3P
Required percentage = (3P/P) × 100 = 300%
Therefore, R is 300% more than P.
