this is a good question

Answer 1

Ananth takes 6 hours to read a book Bharath takes 4 hours to read a book

so, L.C.M = 12

The number of pages read by Ananth and Bharath must be 12 (or) multiple of 12 only.

If Ananth read 12 number of pages in 6 hrs

so, in 1 hr = 12/6 = 2 pages

If Bharath read 12 number of pages in 4 hrs

so, in 1 hr = 12/4 = 3 pages

After 1 hr :- Ananth (read 2 pages, to be read 10 pages)   Bharath (read 3 pages , to be read 9 pages )

After 2 hr :- Ananth (read 4 pages, to be read 8 pages)      Bharath (read 6 pages, to be read 6 pages )

After 3 hr :- Ananth (read 6 pages, TO BE READ 6 pages)      Bharath (read 9 pages, TO BE READ 6 pages)

Hence, after 3 hours is the number of pages TO BE READ by Ananth, twice that TO BE READ by Bharath.

There's a small mistake in the ans
 After 3 hr :- Ananth (read 6 pages, TO BE READ 6 pages)      Bharath (read 9 pages, TO BE READ * 6 pages*)
it is 3 pages to be read by Bharath
