Answer: (2) Rs.2700.00 

Solution:-
The height of a wall = 12 feet 
The length of the wall = 15 feet

The area of a face of a wall = 12 x 15 
= 180 square feet 

If the painting charges are Rs.15 per square feet. 
Then, the cost of the painting one face of the wall = 180 x 15
 = Rs.2700.00

Hence, the correct answer is option (2) Rs.2700.00.
