Answer» Time TAKEN by 15 persons to do a job = 30 DAYS ⇒ Time taken by 1 person to do a job = 30 × 15 = 450 days ⇒ Time taken by 1 person with twice the efficiency = 450/2 = 225 days ⇒ Time taken by 30 persons with twice the efficiency = 225/30 = 7.5 days ∴ Time taken by 30 persons with twice the efficiency = 7.5 days |
