A Correct answer
Explanation

As per the instructions, only those areas which measure less than 100 sq. m are to be painted with plastic paint. Hence, the rooms which measure less than 100 sq. m are kitchen and the two bathrooms. Paint cost of kitchen = 12 m x 14 m (Height of the room) x 2 (Two walls of the same size) + 6 m x 14 m (Height of the room) x 2 (Two walls of the same size) = 336 sq. m + 168 sq. m = 504 sq. m x Cost of plastic paint at Rs. 120 per sq. m  = Rs. 60480 Paint area of bathroom = 8 m x 14 m (Height of the room) x 2 (Two walls of the same size) + 7 m x 14 m (Height of the room) x 2 (Two walls of the same size). = 224 sq. m + 196 sq. m = 756 sq. m x Cost of plastic paint at Rs. 120 per sq. m  = Rs. 50400 x 2 (as two bathrooms ae there) = Rs. 100800. Hence, total cost of plastic paint = Paint cost of kitchen + Paint cost of two bathrooms = Rs. 60480 + Rs. 100800 = Rs. 161280
