Question

Assume any number $x$, add 7 to it, multiply by 2, add 2, divide by 2, finally subtract $x$.

The number we get after all the operations is ___.

• A. 6
• B. 7
• C. 8
• D. 9

Answer 1

The correct option is C 8

Given statement can be mathematically represented as
= $\frac{\left(\right[[x+7]\times 2]+2)}{2}$ - $x$
= [($x+7$] + 1) - $x$ = $x$ + 8 - $x$ = 8
