A Correct answer
Explanation

As per the instructions: Total renovation cost for General Manager’s room = Cost of painting of the four walls and ceiling + Cost of granite flooring

= 23 m x 14 m x 2 (two walls of the same size) + 27 m x 14 m x 2 (two walls of the same size) + 23 m x 27 m x cost of painting at Rs. 210 per sq. m + 23 m x 27 m x cost of granite at Rs. 240 per sq. m = 644 sq. m + 756 sq. m + 621 sq. m x Rs. 210 + 621 sq. m x Rs. 240 = 2021 sq. m x Rs. 210 + 621 sq. m x Rs. 240 = Rs. 424410 + Rs. 149040 = Rs. 573450
