Arithmetic Aptitude :: Time and Work
- A can finish the job at the same time in which B and C together do it. If A and B together can finish the work in 10 days and C alone can do the work in 50 days, how many days B will take to complete the same job?
- A and B working together can finish a work in 12 days, B and C working together can finish the work in 16 days. If A works for 5 days, B works for 7 days, and C completes the remaining work in 13 days, C alone can complete the work in how many days?
- A can finish a work in 10 days and B can finish the same work in 15 days. If they work alternatively, find the time taken to finish the job.
- A, B, and C individually can finish a job in 10, 15, and 30 days respectively. If A starts the work and continues until the end, B and C work alternatively, in how many days work will be done?
- A can finish a work in 10 days, B can finish the same work in 15 days, and C can finish it in 30 days. All three start working together, but after some days A leaves the job, then after one day B also left the job. C completes the remaining job in 3 days. Find the number of working days of B.
- A can finish a work in 8 hours, B can finish the same work in 12 hours, and C can do it in 24 hours. All the three starts work at 3 am, 4 am, and 5 am respectively. At what time work will be completed?
- A and B work separately in 15 hours and 12 hours respectively. Another man C can destroy the work in 4 hours. If they start doing work at 8 am, 9 am, and 11 am respectively. At what time the total work will be destroyed?
- A can complete a wall in 30 hours. B uses 30 bricks per hour, and together they can finish the wall in 12 hours. How many bricks are in the wall?
- A and B can complete a wall in 15 and 20 hours respectively. If they work together, the wall is completed in 12 hours and they use 280 less bricks. Find the total number of bricks in the wall.
- The efficiency ratio of A, B, and C are 2:3:4. To finish a job A takes 10 days more than B, if they work together, the work will be completed in how many days?
