Let the age of Mrinal be x Statement 1: Age of Mrinal’s Mother = x + 20 Statement 2 Age of Mrinal’s brother = x – 3 As we don’t know the age of either Mrinal’s mother or Mrinal’s brother. We can’t calculate the age of Marinal with the given data. ∴ Statement 1 and 2 together are not sufficient, and additional data is needed to answer the question.
