46.

Pawan is twice as fast as anil and can complete a piece of work in 15 days less time than anil

Answer»

So,

I am assuming that the ENTIRE question is how many days will it take to complete the task if they work together

Now,

Pawan can complete a task in 15 days and he is twice as fast as Anil

So,

Anil will complete the same amount of work in 30 days

Now,

If they work together, LET the days taken to complete the same task be x,

1/x = 1/15 + 1/30

1/x = (30 + 45)/(15×30)

1/x = 75/(15×30)

x=(15 × 30)/45

x = 10

So, they can complete the work in a period of 10 days
