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

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?

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. 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?

    • 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’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
