$13$

Short Answer

Expert verified

The correct answer of this question is C $3$ .

Step by step solution

Step 1. Find the value of n to get solution of the equation.

In this, Solve the given equation and find the value of n to get the correct answer.

Step 2. Find the solution of the equation

Here, The expression is simplified as:

$\begin{array}{l} 鈭� 4 (n + 5) = 鈭� 32 \\ 鈭� 4 n 鈭� 20 = 鈭� 32 \\ 鈭� 4 n = 鈭� 32 + 20 \\ 鈭� 4 n = 鈭� 12 \\ n = \frac{鈭� 12}{鈭� 4} = \frac{鈭� 12}{鈭� 4} \\ n = 3 \end{array}$

Step 3. Eliminating the options to get correct one
