If P, Y and Z are weights of cement, fine aggregates and coarse aggregates respectively and W/C is the water cement ratio, the minimum quantity of water to be added to first batch is obtained by the equation
A. 0.1P + 0.3Y + 0.1Z = $\frac{\mathit{W}}{\mathit{C}}\times$ P
B. 0.3P + 0.1Y + 0.01Z =$\frac{\mathit{W}}{\mathit{C}}\times \mathit{P}$
C. 0.4P + 0.2Y + 0.01Z =$\frac{\mathit{W}}{\mathit{C}}\times \mathit{P}$
D. 0.5P + 0.3Y + 0.01Z =$\frac{\mathit{W}}{\mathit{C}}\times \mathit{P}$
