Answer 2

Answer:

Let the total pages be 'x' in number.

According to condition 1:

3/8*x read on first day.

So remaining pages will be :

1-3/8*x

=5/8*x

According to condition 2:

Read 4/5 of remaining

So left unread =1/5 of remaining

Therefore remaining at last=1/5 * 5/8*x

=1/8x

Unread=30

Therefore:1/8*x = 30

>> X=240.

Therefore total page is240
