Question

Amy read a book during vacation She read 2/9 on the first day , 3/7 of the remainder on the second day and 1/2 of the rest on the third day .There are 136 pages left how many pages were in the book?

Answer 1

Answer:

612 pages

Step-by-step explanation:

let the no of pages be x

part read on 1st day =2x/9

thus part left = x-2x/9 = 7x/9

again she reads 3/7 of the remainder and remainder = 7x/9

thus part read now is (3/7)×7x/9 = x/3

part left now is 7x/9-x/3 =4x/9

she again reads 1/2 of the rest that is 4x/9

thus part read now = 2x/9 so part left = 4x/9 - 2x/9 = 2x/9

now we know 136 pages are left and 2x/9 part is left

so we have 2x/9= 136

=>x= (136×9)/2 = 68×9 = 612

thus the book had 612 pages.

my God very big book.
