The average age of 24 workers and their supervisor is 41 years. If the supervisor's age is excluded, the average reduces by 0.75 years.
Formula used:
Average = Total Sum / Number of Individuals
Calculation:
Let the supervisor's age be S years.
Total Sum of Ages including the supervisor = 41 × 25
⇒ 41 × 25 = 1025
Total Sum of Ages excluding the supervisor = 40.25 × 24
⇒ 40.25 × 24 = 966
Supervisor's age, S = Total Sum including the supervisor - Total Sum excluding the supervisor
⇒ S = 1025 - 966
⇒ S = 59 years
∴ The correct answer is option (2).
