  1. 30
  2. 18
  3. 24
  4. 36

Problem 2.

A and B working alone 7 hours a day can complete a job in 8 days and 6 days respectively. In how many days would they finish the job if they work together 8 hours per day?

  2. 3
  3. 3.6
  4. 4

Problem 3.

If 8 men working together 8 hours per day for 8 days produce 8 units of work, the units of work produced by 4 men working together 4 hours per day for 4 days is,

  1. $1$
  2. $4$
  3. $\displaystyle\frac{1}{2}$
  4. $\displaystyle\frac{1}{4}$

Problem 4.

  2. Rs.350; Rs.50
  3. Rs.150; Rs.250
  4. Rs.200; Rs.200

Problem 5.

A cistern is filled up by two inlet pipes, working separately, in 30 mins and 20 mins respectively, while it is filled up in 18 mins with both pipes working together but the second pipe closed off after some time. After how much time is the second pipe closed?

  1. 12 mins
  2. 8 mins
  3. 5 mins
  4. 10 mins

Problem 6.

Working 9 hours a day for 20 days a team of 8 men finish a job completely. How many days would a team of 7 men take to complete the same job working for 10 hours a day?

  1. $20\displaystyle\frac{4}{7}$
  2. $20\displaystyle\frac{1}{2}$
  3. $20\displaystyle\frac{3}{5}$
  4. $20\displaystyle\frac{3}{7}$

Problem 7.

Three inlet pipes to a cistern with diameters $2$cm, $1$cm and $1\displaystyle\frac{1}{3}$cm fill the cistern with inflow rate of each pipe poroportional to the square of its diameter. If the pipe with the largest diameter can fill the cistern working alone in 61 mins, how much time will be taken by the three pipes to fill the cistern working together?

  1. 36 mins
  2. 32 mins
  3. 38 mins
  4. 34 mins

Problem 8.

In 18 days, working together, A, B and C earn a sum of Rs.2700. If on the same job, B and C together earn Rs.1520 in 20 days and, C and A together earn Rs.940 in 10 days, how much does C earn in a day?

  1. Rs.40
  2. Rs.15
  3. Rs.10
  4. Rs.20

Problem 9.

Working 6 hours a day, 12 pumps can empty a completely filled reservoir in 15 days. How many such pumps working 9 hours a day can empty the same completely filled reservoir in 12 days?

  1. 10
  2. 9
  3. 15
  4. 12

Problem 10.

A cistern is filled by three inlet pipes A, B, and C working together for 6 hours. Once, after the three work together for 2 hours, the pipe C is closed and then on, the pipes A and B fill the remaining part in 7 hours. How much is then the time taken by C alone to fill the cistern?

  1. 16 hours
  2. 10 hours
  3. 12 hours
  4. 14 hours
