Question

If A can complete a work in 10 days and B is 100 faster than A. How much time B will take to complete the work?


​

Answer 1

Answer:

1/10 th of a day

Step-by-step explanation:

B is 100 times faster than A

if  A completes a work in 100 days, B can complete in 1 day.

if A completes in 1 day, B can do in 1/100 th of a day

if A completes in 10 days, B can do in 1/100 *10 = 1/10 th of day

Answer 2

Answer:

Let, the whole of the work be 1

Now,

A's one day's work = 1/10 part

B's one day's work = 1*100/10 part

=10 times of the

A's rate of work

So, B will take 1/10 days to complete the same work as done by A

We know,

1 day = 24 hrs

1/10 day = 24/10 = 2.4 hrs

= 2 hrs 4*60/10 mins

2 hrs 24 mins (answer)
