Question
A textbook has a total of 892 pages. It is divided into
two parts. The second part of the book has 52 pages less than the first part. How many pages are there in the second part of the book?Solution
ATQ, Let the first part of the book have x pages. The second part has 52 pages less, so it has x - 52 pages. The total pages in the book are 892, so: x+(x−52) = 892 2x−52=892 2x=944 X = 472 So, the first part has 472 pages. The second part has = 472−52=420 So, the second part has 420 pages.
