    Please help me with question 4

    • Animesh Jha

      Had there been no baby then the present average age of family of 5 members would be 20 yrs. However due to addition of 6th member the average age reduced by 3 yrs.
      The age of 6th member will be such that it reduces average age by 3 yrs.
      Hence age of 6th member = 17-(3*5) = 2 years…
      There was a typo in the question that has been rectified..
