Question

The left and right page numbers of an open book are two consecutive integers whose sum is 563 Find these page numbers

Answer 1

281 and 282

Explanation:

Let the two numbers be x and x+1.

ATQ,

x+x+1=563

2x+1=563

Subtract 1 from both sides.

2x+1-1=563-1

2x=562

x = 281

First page number = 281

Other page number = 281+1 = 282

Hence, these page numbers are 281 and 282.
