Question

The sum of the page numbers of two consecutive pages of a book is 149. Find the page numbers.

• A. 70, 71
• B. 74, 75
• C. 76, 77
• D. 78, 79

Answer 1

The correct option is B 74, 75

Let one page number be $x$.
Then , the other page number is $x+1$.

According to the question,
$\Rightarrow x+(x+1)=149\Rightarrow 2x+1=149\Rightarrow 2x=149-1\Rightarrow 2x=148\Rightarrow x=\frac{148}{2}\Rightarrow x=74$

Hence, one page number is 74 and the other page number is $x+1=74+1=75$.
