Explanation

Total cost of renovation of the service desk room = [cost of wall paper on four walls] + [cost of ceiling painting] + [cost of flooring] = [31 m x 12 m x 2(two walls of the same size) + 23 m x 12 m x 2(two walls of the same size) x cost of wall paper at Rs. 235 per sq. m] + [31 m x 23 m x cost of ceiling painting at Rs.190 per sq. m] + [31 m x 23 m x cost of marble flooring at Rs. 280 per sq. m] = [1296 sq. m x Rs. 235] + [713 sq. m x Rs. 190] + [713 sq. m x Rs. 280] = Rs. 304560 + Rs. 135470 + Rs. 199640 = Rs. 639670
