Question

A can finish a job in 3 days where as B fimishes it in 6 days.The time taken to complete the job together is ?

Answer 1

Answer:

4 days is the correct answer to the question

Answer 2

The time taken to complete the job together is 2 days.

Step-by-step explanation:

Since we have given that

Number of days in which A can finish a job = 3 days

Work done by A in 1 day = $\dfrac{1}{3}$

Number of days in which B can finish a job = 6 days

Work done by B in 1 day = $\dfrac{1}{6}$

We need to find the time taken to complete the job together.

So, Total work would be

$\dfrac{1}{3}+\dfrac{1}{6}\\\\=\dfrac{2+1}{6}\\\\=\dfrac{3}{6}\\\\=\dfrac{1}{2}$

Hence, the time taken to complete the job together is 2 days.
