Question

Rakesh reads 2 /9 of book on on Friday, 1 /3 of it on Saturday and the remaining 160 pages on Sunday .How many pages does the book have in all ?​

Answer 1

Step-by-step explanation:

Let the no. of pages be x

then on Friday he read =2/9 * x

and on Saturday he read = 1/3 * x

so, according to question

x - ( 2x/9 + x /3 ) = 160

x - ( 2x +3x/9 )=160

x - (5x/9 )=160

9x - 5x/9 =160

4x/9 =160

x = 160*9/4

x = 40*9

x = 360

so, answer is 360
