- Initial average calculation:

- Four years ago, with five members, the average age was 38.

- Total age of these five then: 5 members × 38 years = 190 years.

- Present total age for these five: 190 years + (5 members * 4 more years) = 210 years.

- Adding new member:

- Present average age becomes 44 years with six members.

- Total present age with new member: 6 members × 44 years = 264 years.

- Calculating new member’s age:

- New member's present age: 264 years - 210 years = 54 years.

- Evaluating the options:

- ?? Option 1: 74 - Incorrect, it's too high.

- ?? Option 2: 52 - Incorrect, it's slightly low.

- ?? Option 3: 30 - Incorrect, significantly lower.

- Option 4: 54 - Correct!

Thus, the present age of the new member is 54 years.
