3/8 of a book on one day and 4/5 of the remain another day if there were 30 period under unread how many pages did the book contain
Answers
Fraction of pages read on the first day:
First day = 3/8
Fraction of the book remaining after first day:
Remaining = 1 - 3/8 = 5/8
Fraction of the book read on the second day:
Second day = 4/5 x 5/8 = 1/2
Fraction of the book remaining after second day:
5/8 - 1/2 = 1/8
Find the total number of pages:
Pages remaining = 1/8 of the book
Pages remaining = 30 pages
1/8 of the book = 30 pages
8/8 of the book = 30 x 8 = 240 pages
Answer: There are 240 pages in the book.
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
