Correct Answer - Option 4 : 360
Given
Temporary employees = 126
Formula Used
Percentage = (Required/Total) × 100
Calculation
Let the total number of employees is 100%,
Then according to the question,
Experienced employees = 75%
Inexperience employees = 25%
Permanent employees = 20% of inexperienced employees + 80% of experienced employees
⇒ 20% of 25% + 80% of 75%
⇒ 1/5 × 25% + 4/5 × 75% = 5% + 60% = 65%
So the temporary employees be 35%
⇒ 35% = 126
⇒ 100% = 126/35 x 100 = 360
∴ The required number of employees is 360.
