Question

$-36=12(1+p)$

What is the value of $9(1+p)$ ?

• A. -27
• B. 27
• C. -3
• D. $-\frac{27}{4}$

Answer 1

The correct option is A -27

First we note that the R.H.S of the given equation is very similar to desired expression, except it is multiplied by 12 instead of 9.

$-36=12(1+p)$

Then we multiply both sides by $\frac{9}{12}$

$-36\times \frac{9}{12}=12(1+p)\times \left(\frac{3}{12}\right)$

$-27=9(1+p)$

Thus the value of $9(1+p)=-27$.
