      Question

      Two numbers are in the ratio 3:7. The product of their

      H.C.F. and L.C.M. is 2541. The sum of the numbers is:
      A 110 Correct Answer Incorrect Answer
      B 182 Correct Answer Incorrect Answer
      C 171 Correct Answer Incorrect Answer
      D 154 Correct Answer Incorrect Answer

      Solution

      Let the numbers be 3x and 7x respectively. First number Γ— second number = HCF Γ— LCM => 3x Γ— 7x = 2541 => x2Β = [2541/(3Γ—7)] = 121 => x = √121 = 11 Sum of the numbers = 3x + 7x = 10x = 11 Γ— 10 = 110
