Question
2 assistants are as efficient as one senior officer. If 40
assistants prepare 100 reports in 5 days, how many senior officers are needed to prepare 100 reports in 2 days?Solution
ATQ,
Let the efficiency of each assistant be 'x' units/day
Efficiency of each officer = 2x units/day
Let the number of officers be 'm'
(40x × 5)/100 = (2x × m × 2)/100
⇒ 4m = 200
⇒ m = 50
Therefore, 50 senior officers are needed to complete the reports in 2 days.
