Explanation: I. Material cost per m2 = Rs. 2.50,2. The cost of labour is Rs. 3500.The total cost of the project is Rs. 14,500.Let's say the area is A square metres. (14500 - 3500) = Rs. 11,000 in material costs,A = 11000 x 2 /5 = 4400 m2. 5A/2 = 11000 A = 11000 x 2 /5 = 4400 m2.As a result, all of I, II, and III are required to obtain the solution.
