Question

A can complete a work in 12 days and b can complete the same work in 8 days.what part of the work will they all together complete in 1 day?

Answer 1

Answer:

5/24 part of work.

Step-by-step explanation:

We have,

Time taken by A to complete a work = 12 days

Time taken by B to complete the same work = 8 days

So,

The work done by A in one day = 1/12

and,

Work done by B in one day = 1/8

also,

Let us say the time taken by both of them to complete the work working together be = x

So,

Work done by them together in one day = 1/x

So,

$\frac{1}{12}+\frac{1}{8} = \frac{1}{x}\\\\\frac{2+3}{24}=\frac{1}{x}\\\\\frac{5}{24} = \frac{1}{x}\\ \\x = \frac{24}{5}$

Therefore, work done by both of them working together in one day will be = 5/24.
