Correct choice is (d) 93.8
The best explanation: The quantity of cement required is [1/(1+2+4)] x 1.52 x 15 m^3 i.e. 3.257 m^3. SP weight of concrete is 1440 kg/m^3 and the weight of one cement bag is 50 kg. Therefore, the number of cement bags required for RCC (1:2:4) for 15 m^3 of work is 3.257 x 1440/50 = 93.8 bags.
