Since Arnav's time was never given, it can be concluded that he simply gave up, walked out of the room, and dropped the class.
Or he never showed up to solve the problem.
And yet another trick question designed to test your visual acuity.
A tank can be filled by the Tap A in 4 Hrs and by Tap B in 6 Hrs. The same tank can be emptied by the Tap C in 8 Hrs. Now suppose we keep all three taps on then how much time it will take to fill?
A tap can fill a tank in 30 minutes, another tap can fill it in 1.5 hours.
If both the taps are opened at 11.40 am.
At what time will the tank be filled?
A and B can complete a work in 12 days. B and C can complete the same work in 18 days. C and A can complete in 24 days. How many days will take for A, B and C combined together to complete the same amount of work?
Rohit and Virat, working together, can complete an assigned task in 20 days.
If Rohit worked alone and completes half the task and then Virat takes over and completes the remaining half, then the task gets completed in 45 days.
How long will Rohit take to complete the task is he worked alone?
Assume that Rohit is more efficient then Virat.
