Question

vivek reads 2/7 of a book on one day and 5/16 of remaining on next day .if 275 pages of the book were still left unread how many pages did the book contains
​

Answer 1

Answer:

685

Step-by-step explanation:

Let us assume that the total number of pages are x.

ATQ,

(2x/7)+(5x/16)+275=x

By solving, we get

32x+35x+30800=112x

112x-32x-35x=30800

45x=30800

x=30800/45=684.45

Therefore, the value of x is 685 (approx.).
