Question

I want correct answer =18/5days​

Answer 1

Answer:

Answere is 18/5 days

Step-by-step explanation:

A can complete a work in 6 days

B can complete a work in 9 days.

Suppose that the total work is 18. Which is 9 and 6 l.C.M also.

A complete a work in 6 days and total work is 18. So a complete 3 work in a day.

-:

$\frac{18}{6} = 3$

B complete a work in 9 days and total work is 18.

So b complete 2 work in a day.

-:

$\frac{18}{9} = 2$

Capacity of A = 3

Capacity of B = 2

Total capacity of both = 3+2 = 5

Total work = 18

Then days of working together =

$\frac{18}{5}$

Answere = 18/5
