The correct answer is option ''B''.

(W/C)------> weight of water to the weight of cement.

W/c ratio.

Weight of water to Weight of cement.

Answer B is correct.

Because,

Water : 1000 kg -> By weight. 1m3 -> By Volume
Cement : 1440 kg-> By weight 1m3 -> By Volume
And the Ratio : 0.694 : 1

Both rations are not same So that the answer E is definitely wrong.

The Density of these both i.e. water & Cement is different, therefore w/c ratio cannot be calculated by using its volume so, the ans. A is also wrong.

Finally, B is the correct answer.

The correct answer is only option B.

Actually 1m3 of the volume contain 1000 kg of water or 1000 liters of water. So both weight and volume will be correct.

By weight only. So, the correct Answer is B.

In small work, we measure in volume.

And in mass work, we measure in weight to eliminate the bulking of sand.

Therefore E is correct.

Weight = Unit Weight x Vol.
Water Unit Weight = 1000 Kg/m3.
But Cement Unit Weight = 1440 Kg/m3.
So, 1000 Kg Water = 1 m3 Water.
But, 1440 Kg Cement = 1m3 Cement.

So, I think Option B is Correct. Weight of Water to Weight of Cement.
