C is right.
Because of a density of water is 1kg/lit.
So 30kg=30Lit.
Because of a density of water is 1kg/lit.
So 30kg=30Lit.

Since Water cement ratio = weight of water/weight of cement.
(Note: the unit of weight is kg and unit of volume is lit)
The weight of 1 bag (vol -35 lit or 0.035 CuM) of cement is= 50kg.
The weight of 30 lit of water = 30 kg (since the density of water is 1kg/lit).
Therefore, W/C ratio = 30 kg(weight)/50 kg (weight) = 0.6 (Answer).
Option 'C' is the right answer!

The density of water is 1000kg/m^3.
And 1 m^3 equals to 1000 litres.
1 litre of pure water has a weight of 1 kg.
We know that the density of pure water is 1000 k g/m 3.
It means 1 cubic meter of pure water has a weight of 1000 kg.

Water cement ratio is weight ratio of water & cement.

The water-cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
So 30/50=0.6 (option C is correct).
So 30/50=0.6 (option C is correct).

w/c ratio is the weight of water to weight of cement not the volume of cement.
So, 30/50 =0.60.
1 bag of cement is 50 kg & 35 ltr.
So, 30/50 =0.60.
1 bag of cement is 50 kg & 35 ltr.

W/c ratio is measured in kg/l, so option C is correct.

W/c ratio is measured in lit/kg.
Answer must be C.
Answer must be C.
