Question

after reading 5/8 of a book 168 pages are left how many pages are there in all in the book.

Answer 1

Let P be total number of pages in book.

Book read = 5/8 P
Book left to read= P- 5P/8= 3P/8

given
3P/8= 168
3P = (168x 8)
P = 8x (168/3)
P= 8x (56)= 448

Answer 2

hi

let the total pages be x

After reading 5/8 of a book 168 pages are left

so lets form an equation

x = 5x/8 + 168

x - 5x/8 = 168

3x/8  = 168

x = 168*8/3

x = 448 pages

hope it helps u
