Hint: We have given the cost of a cellphone as Rs. 999 and are asked to find the cost of 12 such cellphones which we are going to multiply Rs. 999 by 12. Now, multiply them and match the answer with the option given in the answer. You can understand the concept which we have used above as we know the cost of 1 cell phone and asked to find the cost of 12 cellphones.

Complete step by step answer:
The cost of 1 cellphone given in the above problem is as follows:
Rs. 999
Now, we are asked to find the cost of 12 cellphones which we are going to find by multiplying 12 by Rs. 999 so multiplying 12 by Rs. 999 we get,
$Rs.\left( 999\times 12 \right)$
The result of the multiplication of the above expression is as follows:
Rs. 11988
From the above solution, we got the cost of 12 cellphones which is equal to Rs. 11988.

So, the correct answer is “Option d”.

Note: The other way in which the above question is presented is that we have given the cost of 12 cellphones and are asked to find the cost of 1 cellphone which we are going to find by dividing the cost of 12 cellphones by 12. Let us see, how it’s going to happen:
Let us consider we have given the cost of 12 cellphones as Rs. 11988 and are asked to find the cost of 1 cellphone so we are going to divide Rs. 11988 by 12 we get,
$\begin{align}
  & Rs.\dfrac{11988}{12} \\
 & =Rs.999 \\
\end{align}$
