* WT of 30 l water = 30 kg.
* WT of 1 bag cement = 50 kg.
So, 30/50 = 0.6.

Wt of 1bag cement = 50 kg.
Wt of 30litre water = 30 kg.
Wc ratio = wt of water /wt of cement = 30/50.
Wc ratio = 0.6.

Density of water =1000kg/m3.
volume of water = 30 litres = 30/1000 m3.
weight of water = 1000 x 30 /1000 = 30kg.
W/C ratio = 30/50 = 0.6

So, 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.

1lit = 1kg so w/c ratio is;

W/c = 30/50 = 60.

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

Vikas said:   8 years ago
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.

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

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.

30/50 = 0.60 is the correct answer.
