If 20% of P is added to 40% of Q, then the resultant comes as 80% of Q. P is what percentage of Q?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 200%.
0.20P + 0.40Q = 0.80Q
⇒ 0.20P = 0.40Q
⇒ P = 2Q
Required percentage = (P/Q) × 100 = (2Q/Q) × 100 = 200%
