Question

If a man takes 15 days to complete a piece of work, what part of the work will 2 men complete in 5 days?​

Answer 1

Answer:

1 man takes 15 days

2 man will take half i.e 7.5 days

the work of 2.5 days will be left

Answer 2

Answer:

2/3 rd work

Step-by-step explanation:

Since , a man takes 15 days to complete a piece of work

∴ Total work the man will do will be = $1 \times 15$

                                                           = 15 work

∴ The total work is 15

Now , we have to find  part of the work completed by 2 men in 5 days

∴ The two men in 5 days will complete $2 \times 5$ work respectively.

                                                       = 10

Now, the part of work completed be 2 men in 5 days as compared to total will be  $\frac{10}{15}$  th of total work

= $\frac{2}{3}$ of total work
