RRB NTPC · Question 32

If P = 2 + 0.2 ÷ (0.2 × 2) - 1 × 2 Q = 2 - 0.2 ÷ (0.2 × 2) - \(\frac{1}{2}\) × 2, then \(\frac{P}{Q}\) is the equal to:

  1. 1.0

  2. 1.5

  3. 0.5

  4. -0.5

Show answer & explanation

Answer: (A) 1.0

Explanation

P = 2 + 0.2 ÷ 0.4 − 2 = 2 + 0.5 − 2 = 0.5. Q = 2 − 0.5 − 1 = 0.5. So P/Q = 1.0.
