The sum of the page numbers on the facing pages of a
book is 373. What are the page numbers?
(Hint:Let the page numbers of open pages are
x and x + 1)​

Answer 1

let's the page numbers of open pages are x and x+ 1,

sum of the page numbers on the facing pages of a book=373

x+x+1=373

2x+1=373

2x=373-1

2x=372

x=372/2=186

x=186,x+1=186+1=187
