      Question

      The LCM of two numbers is 2250 while their HCF is 50.

      If one of the numbers is 450, then the other number is:
      A 250 Correct Answer Incorrect Answer
      B 500 Correct Answer Incorrect Answer
      C 600 Correct Answer Incorrect Answer
      D 800 Correct Answer Incorrect Answer

      Solution

      Given:
      - LCM of two numbers = 2250
      - HCF of two numbers = 50
      - One number = 450
      Since,
      HCF of two numbers × LCM of two numbers = First number × Second number
      Second number = (50 × 2250) / 450 = 112500 / 450 = 250
      So, the other number is 250.
