Question

the sum of the page numbers on the facing pages of a book is 373.what are the page numbers

Answer 1

Let the first page be "x" and the second page be "x+1"

Sum of those = 373.

x + x+1 = 373

2x+1 = 373

2x = 373 - 1

2x = 372

x = 372/2

x = 186.

So the pages are x=186 and x+1 =186+1= 187.

Answer 2

Facing page numbers should be consecutive numbers
Let two numbers are x and x+1
Sum=373
x+x+1=373
2x=373-1
2x=372
x=372/2
x=186
Therefore
Required facing page numbers are 186and 187
