Question

the left and right page numbers of an open book are two consecutive integers whose sum is 211. find these page numbers.

Answer 1

105 and 106

Explanation:

The consecutive pages are such that the difference between the numbers of these pages is 1. As such, if the number on the first of the two pages is x, the second will be x + 1.

Hence, given that the sum of the numbers two pages is 211,

x + x + 1 = 211

2x = 210

x = 105, the next

= 105 + 1

= 106
