Question : 21 of 40

Marks: +1, -0

Rohan takes twice as much time taken by Sahil and Pulkit does it in the same time as Rohan and Shail working together. If individually Rohan finish the work in 3 days, then the time taken by alone three working together is:

1 day
$1 1/3$ day
2 days
$2 2/3$ days
$/3$ day

Validate

Solution:

Time taken by Rohan = 3 days
Time taken by Sahil = 6 days
Time taken by Pulkit =

1/3 + 1/6

{2+1}/{6}

3/6

1/2

= 2 days
Work done by all the three together in one day
=

1/3 + 1/6 + 1/2

{2+1+3}/6

6/6

= 1
So, together they finish the work in 1 day.
