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.

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!

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.

30/50 = 0.60 is the correct answer.

Here ask only water-cement ratio but you have said density of 1bag of cement so, water cement ratio of 1bag cement is 0.60,
1bag=50kg,
50/30=0.60.
1bag=50kg,
50/30=0.60.

1 bag cement= 34.5L. Again so w:c= 30L/34.5L, = 0.86.
So Correct option is :-D.
So Correct option is :-D.

Since, the density of water =1kg/L.
(W/C) the ratio is taken in weight not in volume.
Wt of 30L of water = 30 kg.
And, w/c =30/50=0.6.
So, C is correct.
(W/C) the ratio is taken in weight not in volume.
Wt of 30L of water = 30 kg.
And, w/c =30/50=0.6.
So, C is correct.

Water cement ratio = wt.of water/wt. of cement.
= 30/50 = 0.60,
Option c is correct.
= 30/50 = 0.60,
Option c is correct.

WE KNOW W/C RATIO = WEIGHT OF WATER / WEIGHT OF CEMENT.
AND WE ALSO KNOW 30 LTR WATER = 30 KG WATER.
THEN W/C RATIO = 30/50 = 0.6.
AND WE ALSO KNOW 30 LTR WATER = 30 KG WATER.
THEN W/C RATIO = 30/50 = 0.6.

1lit = 1kg so w/c ratio is;
W/c = 30/50 = 60.
W/c = 30/50 = 60.
