      Question

      P and Q are two numbers. Their average is 420, and the

      sum of P and Q is 200% of P. What percentage of P is the difference between P and Q?
      A 22% Correct Answer Incorrect Answer
      B 20% Correct Answer Incorrect Answer
      C 29% Correct Answer Incorrect Answer
      D None of these Correct Answer Incorrect Answer

      Solution

      ATQ;

      Since P + Q = 200% of P

      So, P : Q = 1 : 1

      (P βˆ’ Q) : P = 0 : 1

      Therefore,

      0/1 Γ— 100% = 0%
