According to the question, Total work to be done = (5/6) × 28 × 18 × 5 = 2100 units. For I: Number of typists = 32 Desired number of hours = 2100/(15 × 32) = 4.375 hours So, ‘I’ cannot be true. From II: Number of typists = 40 Desired number of hours = 2100/(15 × 40) = 3.5 hours So, ‘II’ cannot be true. From III: Number of typists = 25 Desired number of hours = 2100/(15 × 25) = 5.6 hours So, ‘III’ can be true.
