If P, Y and Z are the weights of cement, fine aggregates and coarse aggregates respetively and W/C is the water cement ratio, the minimum quantity of water to be added to first batch, is obtained by the equation
0.1P + 0.3Y + 0.1Z = W/C x P
0.3P + 0.1Y + 0.01Z = W/C x P
0.4P + 0.2Y + 0.01Z = W/C x P
0.5P + 0.3Y + 0.01Z = W/C x P
0.2P + 0.5Y + 0.1Z = W/C x P
Correct Answer:
0.3P + 0.1Y + 0.01Z = W/C x P
