Detailed Solution
Download Solution PDFGiven:
Total employees = 50
Weight of retired employee = 64 kg
Average weight increase = 250 grams = 0.25 kg
Formula used:
New weight = Old total weight - Retired employee's weight + New employee's weight
Change in average = \(\dfrac{\text{Change in total weight}}{\text{Number of employees}}\)
Calculation:
Change in total weight = Increase in average × Total employees
⇒ Change in total weight = 0.25 × 50 = 12.5 kg
New employee's weight = Weight of retired employee + Change in total weight
⇒ New employee's weight = 64 + 12.5
⇒ New employee's weight = 76.5 kg = \(76\frac{1}{2}\) kg
∴ The correct answer is option (4).
