Question

A half day work in 5 days b work in 10 days means a and b combine to finish work in how many days ?

Answer 1

Step-by-step explanation:

Half of the job is 10/20, which means that A did the other 9/20 in ten days. If A does 9/20 of the job in 10 days, then he does 9/200th of the job each day. To get the entire job done, A needs to work for 200/9 days, or 22 and 2/9 days. A and B start to work together and finish half of the work in 10 days.Hope this would be helpful to you.

Answer 2

Hyy mate......

Here is your answer .....

The work done by A in one day =1/5

The work done by B in one day =1/10

Work done by A and B in one day

$= ( \frac{1}{5} + \frac{1}{10}) \\ \\ = \frac{2 + 1}{10} \\ \\ = \frac{3}{10} \\ \\ time \: taken \: by \: a \: and \: b \: to \: finish \: the \: work \\ = \frac{10}{3} = 3 \frac{1}{3} days$

Hope it will help you....
