(a) Rs.1456.00

(b) Rs.1686.00

(c) Rs.1356.00

(d) Rs.1556.00

The question was posed to me by my school principal while I was bunking the class.

This intriguing question originated from Estimate of Three Roomed and Sixed Roomed Building topic in division Methods of Building Estimate & Estimate of Building of Civil Engineering Drawing

Best answer
Right answer is (c) Rs.1356.00

The explanation is: Quantities of brickwork = LxBxH = 4m x 3m x 0.30m = 3.6 cu.m

Quantity of plastering (two faces) = 2 x 4m x 3m = 24sq.m

Cost of brickwork = 3.6 x 320.00 = Rs.1152.00

Cost of plastering = 24x 8.50 = Rs.204.00

Total cost = 1152.00 + 204.00 = Rs.1356.00.
