Correct Answer - Option 4 : 304 kg
Given:
The average weight of 60 employees = 68 kg
The average reduced = 4 kg
Formula Used:
Average = Sum of total observations/Total number of observations
Calculation:
According to the question, we have
The total weight of 60 employees = 60 × 68
⇒ 4080 kg
Now, after one employee left the company, the average reduced by 4 kg
The average weight of 59 employees = 68 - 4 = 64 kg
The total weight of 59 employees = 59 × 64 = 3776 kg
The weight of an employee who left the company = (4080 - 3776) kg
⇒ 304 kg
∴ The weight of an employee who left the company is 304 kg.
