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?

What is the time taken by B to finish 1 work?

If input is same, more efficiency means more output. In this case, input is time and output is work. B , being 40\% more efficient than A, should produce 40\% more work in a given time. So, time taken by B to finish 1 work (means same as A) = 21/1.4 =15 days.

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 much more efficient is 50\% of 24 days?

Efficient enough to keep A unemployed. If B is 50\% more efficient than A then this means that B takes half of the time that A takes to complete the same work. Hence, 50\% of 24 days would be 12 days. So B can complete the same work in 12 days. Given, A can do a work in 24 days. => B can complete the same work in 16 days.

Can A and B work together to complete a work?

E. None If A and B work together can complete a work in 8/5 days. A started the work alone and completed. 50\% of the work and left the work then B started the work alone and finished the rest of work. They took total 5 days to complete the work. Then in how many days B can complete the work if A is more efficient than A?

How many days does A and B work alone?

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? Solving we get x = 18 days.

What is the ratio of work done by A and B?

The ratio of work done by A and B = 3: 1. The ratio of times taken by A and B to finish a work = 1 : 3. This means that if someone says A is ‘x’ times as good a workman as B, then he will take the time to B to do the same work. The efficiency of work means, “How much work one person can do in one day (expressed in percentage )”.

How many units of work can A and B work on together?

Therefore, working together, they can complete the total work in 6 days. => In one day, A and B working together can finish of 5 units of work, out of the given 30 units.

What is an example of efficiency of work?

Efficiency The efficiency of work means, “How much work one person can do in one day (expressed in percentage)”. For example, a person can do a job in 2 days. In other words, we can say that he can do 50\% of the work in one day.
