RK001:
how?
there is only one book.....
because there were six books left and 12 pages were remaining so each book have 2 pages
you are not understanding the question...... book is only one
OK I understand
I made some Mistake in reading
yes
I will answer myself.
2/7 was read so 5/7 must be unread on 1st day.
2nd day 4/5 was read out of 5/7=4/5*5/7
= 20/35
=4/7
Remaining pages unread =12
So 12 must be 1/7 of total pages(P)
P/7=12
P=12*7
=56 pages.
2nd day 4/5 was read out of 5/7=4/5*5/7

=4/7
