Question

Ananth takes 6 hours and bharath takes 4 hours to read a book. Both started reading copies of the book at the same time. After how many hours is the number of pages to be read by ananth, twice that to be read by bharath? Assume ananth and bharath read all the pages

Answer 1

Answer:

Step-by-step explanation:

Assume the book is of 240 pages.

So, pages read by Ananth in 1 hr

= 240/6 = 40

And pages read by Bharath in 1 hr

= 240/4 = 60

Ananth reads 40 pages per hour and Bharath reads 60 pages per hour.

Number of pages Ananth will complete at the end of each hour −40,80,120,160,200,240.

Number of pages Bharath will complete at the end of each hour −60,120,180,240.

At the end of 3rd hour, Bharath is left with 60 pages and Ananth is left with 120 pages.

So, the answer is 3 hours.
