Answer:

208

Step-by-step explanation:

let x be the smaller number

let y be the bigger number

x + y = 415 eq 1

the two pages facing each other is always got 1 increment, therefore.

y - x = 1

x = y - 1

substitute x to eq 1. to get y(bigger number)

( y - 1 ) + y = 415

2y - 1 = 415

2y = 415 + 1

y = 416/2

y = 208

check x (smaller number)

x = 208 - 1 = 207

x + y = 415

207 + 208 = 415, ok
