Question

A number is multiplied by $6$ and $12$ is added to the product. The result is $84$. Then the number is:

• A. $-12$
• B. $72$
• C. $+12$
• D. $-72$

Answer 1

Answer: (C)

$+12$

Let the number be $x$
Then, $x\times 6+12=84$
$\Rightarrow 6x=84-12=72$
$\Rightarrow x=\frac{72}{6}=12$
Hence required number is $x=12$
