Question

After reading 2/3 of a book,20 pages are left. How many pages are there in the book?

Answer 1

Answer:

60

Step-by-step explanation:

let total no of pages be x

now :

No of pages read = 2/3*x

No of pages left = 20

Thus, total pages =    {2/3*x} + 20 = x

thus, 2x/3 +20 = x

=> 2x+60 =  3x

=> 60 = 3x-2x

Thus, x=60
