      ratio 4:7:12, respectively. If present average age of β€˜A’ and β€˜C’ is 32 years, then find the age of β€˜B’ when β€˜C’ was 30 years old?
      A 12 years Correct Answer Incorrect Answer
      B 8 years Correct Answer Incorrect Answer
      C 10 years Correct Answer Incorrect Answer
      D 9 years Correct Answer Incorrect Answer

      Solution

      Let the present ages of β€˜A’, β€˜B’ and β€˜C’ be β€˜4x’ years, β€˜7x’ years and β€˜12x’ years, respectively. ATQ; (12x + 4x) Γ· 2 = 32 Or, 16x = 64 So, x = 4 So, present age of β€˜C’ = 12 Γ— 4 = 48 years Present age of β€˜B’ = 7 Γ— 4 = 28 years Difference between the ages of β€˜B’ and β€˜C’ = 48 – 28 = 20 years So, age of β€˜B’ when β€˜C’ was 30 years old = 30 – 20 = 10 years
