After A started the work alone, B joined him after 4 days.
Is a twice as efficient as B?
A is twice efficient as B. A and B together do the same work in as much time as C and D can do together. If the ratio of the number of alone working days of C to D is 2:3 and if B worked 16 days more than C then no of days which A worked alone?
How many people can do a piece of work in 24 days?

How long does it take A and B to complete a job?
2) If A and B work together, they will complete a job in 7.5 days. However, if A works alone and completes half the job and then B takes over and completes the remaining half alone, they will be able to complete the job in 20 days. How long will B alone take to do the job if A is more efficient than B?
How can A and B finish a job in 60 days?
A is thrice as good as workman as B and therefore is able to finish a job in 60 days less than B. Working together, they can do it in: Ratio of times taken by A and B = 1 : 3. The time difference is (3 – 1) 2 days while B take 3 days and A takes 1 day. If difference of time is 2 days, B takes 3 days. = 90 days.
How many days does it take to complete A and B?
A takes the rest of one day after every 4 days and B takes the rest of one day after every 5 days. If A and B starts working together, then the work will be completed on In 18 days, both take the rest of 3 days each and the work, done is ( 36 − 6 29) ( 36 − 6 29) part of the work.
What is the total work finished in 18 + 10 days?
They do 2 + 3 = 5 units a day working together, thus they would have finished 90 units in 90/5 = 18 days. Hence the total work was finished in 18 + 10 = 28 days. Example 3: A can do a piece of work in 24 days and B in 20 days but with the help of C they finished the work in 8 days.
How much time does it take to finish a piece of work?
Time taken by A to finish a piece of work is twice the time taken B and thrice the time taken by C. If all three of them work together, it takes them 2 days to complete the entire work. How much work was done by B alone?
How many people can finish the same job in 4 days?
22) 4 men and 2 boys can do a job in 6 2/3 days. 3 women and 4 boys can finish the same job in 5 days. Also 2 men and 3 women can finish the same job in 4 days. In how many days can 1 man, 1 woman and 1 boy finish the work at their double efficiency?
What is the relationship between efficiency and time?
Efficiency and Time are inversely proportional to each other X:y is the ratio of the number of men which are required to complete a piece of work, then the ratio of the time taken by them to complete the work will be y:x
How long does it take to do a bit of work?
Q 1 – A can do a bit of work in 8 days, which B alone can do in 10 days in how long . In how long both cooperating can do it? A’s 1 day work= 1/8, B`s 1 day work = 1/10 ∴ (A+B) 1 day work = (1/8+1/10) = 9/40 Both cooperating can complete it in 40/9 days.
How do you calculate work completed by A and B together?
If one person takes x days to complete a job and another takes y days to complete the job, then together they will complete in (x × y)/ (x + y) ∴ Work completed by A and B together is 6 days.
How much time does Bhim take to complete the work alone?

How to calculate the number of days required to complete work?
For example, if A can do a work in 10 days and B can do the same work in 12 days, then the work will be completed in how many days. One day’s work = 1/10 + 1/12 = (12 + 10)/120 [Taking LCM of the denominators] Then the number of days required to complete the work is 120/22. Note that this is a reciprocal of the fraction of work done in one day.
