      respectively. If the time taken by the car to cover a distance of β€˜20x’ km is 1 hour less than time taken by the bus to cover a distance of β€˜12x’ km, then find the value of β€˜20x’
      A 220 Correct Answer Incorrect Answer
      B 226 Correct Answer Incorrect Answer
      C 215 Correct Answer Incorrect Answer
      D 225 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      According to the question, (12x/10) – (20x/18) = 1 Or, (12x Γ— 9 – 20x Γ— 5) Γ· 90 = 1 Or, (108x – 100x) Γ· 90 = 1 So, x = 11.25 Required value = 20 Γ— 11.25 = 225
