There are 7 members in a family whose average age is 25 years. Ram who is 12 years old is the second youngest in the family. Find the average age of the family in years just before Ram was born?

The total age of 7 family members is 7 × 25 = 175 years. Just before Ram was born, there were 6 family members. However, we only know Ram's current age (12 years) and that he is the second youngest, which means one member is younger than 12 and five are older. Without knowing the individual ages or the age distribution, we cannot determine what the total age was 12 years ago.
