Is 20\% more efficient than B How much time will they working together take to complete a job which a alone could have done in 66 days?
19. A, B and C can complete a piece of work in 24, 6 and 12 days respectively. Working together, they will complete the same work in: A.
Is 30\% more efficient than B How much time will they working together take to complete a job?

Can do a work in 21 days B is 40\% more efficient than a the number of days required for B to finish the same work alone is?
B is 40\% more efficient than….Correct Option: C.
= 21 × | 100 | = 15 days |

Can do a work in 9 days if B is 50\% more efficient than a then in how many days can b do the same?
Now, let us calculate the number of days taken by B to complete x work. Therefore, the total number of days taken by B $\Rightarrow \dfrac{x}{\dfrac{x}{6}}=x\times \dfrac{6}{x}=6$. Hence, the total number of days taken by B is equal to 6 days. Hence option C is the correct answer.
Do a work in 15 days and B in 20 days if they work on it together for 4 days then the fraction of the work that is left is?
It is given that A can do a work in 15 days and B can do a work in 20 days. If A and B have done work for 4 days together then we have to find out the fraction of work left. So, the fraction of work left is 815.
How much time will p & q take to complete the work?
P is 30\% more efficient than Q. How much time will they, working together, take to complete a job which P alone could have done in 23 days? Hence, P & Q together can complete the work in 13 days. The efficiencies of A, B and C are in the ratio 2 : 5 : 3. Working together, they can compete a task in 9 days.
Which is 20\% more efficient p or Q?
The Questions and Answers of P is 20 \% more efficient than Q, how much time will they working together take to complete a job which P alone could have done in 20 days?a)9 daysb)11 daysc)17 daysd)22 dayse)None of theseCorrect answer is option ‘B’.
How long can A and B alone do the work?
If A and B together can complete a work in 18 days, A and C together in 12 days, and B and C together in 9 days, then B alone can do the work in: A and B together can complete a work in 3 days. They start together but after 2 days, B left the work.
How many days does it take to do 20\% work?
P takes 20 days or per day work is 1/20. He is 20\% more efficient hence Q will do work in one day =1/ (20*1.2)=1/24 so together they do 1/20+1/24= (6+5)/120 days . So total work will take 120/11 days=10and 10/11 days.
