Dear Mockbankers

Today in Banker’s Bounty, you will get Time & Work concept and previous year questions.

Step 1: Watch the video prepared by MockBank’s expert.

Step 2: Read the concepts that follow.

Step 3: Put a timer before you solve the previous year questions on decimal and fraction in quiz and record how much time it takes you to solve it.

Step 4: Send us questions in comments section below which took maximum time and we will tell you a faster way to solve it.

If X can do a piece of work in n days, work done by X in 1 day =1/n
If X does 1/n work in a day. X can finish the work in n days.
If X is thrice as good as Y in work,then

• Ratio of work done by X and Y= 3: 1
• Ratio of time taken to finish a work by X and Y = 1 : 3
1. Two pipes A and B can fill a tank in 15 minutes and 20 minutes respectively. both the pipes are opened together but after 4 minutes, pipe A is turned off. What is the total time required to fill the tank?

Question 1 of 10

2. Two pipes A and B can fill a tank in 15 hours and 20 hours respectively while a third pipe C can empty the full tank in 25 hours. All the three pipes are opened in the beginning. After 10 hours, c is closed. In how much time, will the tank be full?

Question 2 of 10

3. A large tanker can be filled by two pipes A and B in 60 minutes and 40 minutes respectively. How many minutes will it take to fill the tanker from empty state if B is used for half the time and A and B fill it together for the other half?

Question 3 of 10

4. A cistern can be filled a tap in 4 hours while it can be implied by another tap in 9 hours. If both the taps are opened simultaneously then after how much time will the cistern get filled?

Question 4 of 10

5. Two pipes A and B can fill a cistern in 12 minutes and 15 minutes respectively while a third pipe C can empty the full tank in 6 minutes. A and b are kept open for 5 minutes in the beginning and then C is also opened. In what time is the cistern emptied?

Question 5 of 10

6. Two pipes A and B can fill a tank in 6 hours and 4 hours respectively. If they are opened on alternate hours and if pipe A is opened first, in how many hours, the tank shall be full?

Question 6 of 10

7. Three taps A, B and C can fill a tank in 12, 15 and 20 hours respectively. If A is open all the time and B and C are open for one hour each alternately, the tank will be full in:

Question 7 of 10

8. A booster pump can be used for filling as well as for emptying a tank. the capacity of the tank is 2400 m3. The emptying capacity of the tank is 10 m3 per minute higher than its filling capacity and the pump needs 8 minutes lesser to empty the tank than it needs to fill it. What is the filling capacity of the pump?

Question 8 of 10

9. A leak in the bottom of a tank can empty the full tank in 8 hours. An inlet pipe fills water at the rate of 6 litres a minute. When the tank is full the inlet is opened and due to the leak, the tank is empty in 12 hours. How many litres does the cistern hold?

Question 9 of 10

10. Two pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 3 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. the capacity of the tank is:

Question 10 of 10

1. A’s 2 day work=1/90
B’s 1 day work=1/40
C’s 1 day work=1/12
divide 240 in ratio 1/90:1/40:1/12
LCM(of 90,40 12)=360
A:B:C=360*1/90:360*1/40:360*1/12
A:B:C=4:9:30
A’a share=4*240/43 = Rs 22.32
B’s share=9*240/43 = Rs 50.23
C’s share=30*240/43 = Rs 167.44

2. Q. A can do a piece of work in 90 days, B in 40 days and C in 12 days. They work for a day each in turn, i.e. ﬁrst day A does it alone, second day B does it alone and 3rd day C does it alone. After that the cycle is repeated till the work is ﬁnished. They get Rs 240 for this job. If the wages are divided in proportion to the work each had done. Find the amount A will get?
