If A reaches the building at 9:08 am and Lift 1 is at the 6th floor with only B in it, at what time can A at the earliest leave from office on that given day ?
Explanation:
The lift takes 1 minute to reach on 8th floor(where B gets down) and halts for 30 seconds there. Now the lift takes 4 minutes to reach Groundd floor Where A bords the lift and halts for 30 seconds. After that lift takes another 1 minute to reach the second floor. So the total time taken by lift = 1 + 0.5 + 4 + 0.5 + 1 = 7 minutes This means A will reach office by 9:15 and can leave office by 5:45. Hence, option (d).
