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.

1 BAG = 35 LITRES = 50 KG.
For finding W/C ratio units,
W/C = 30/35 (in liters).
= 0.86.
Option "D" is the correct answer.
For finding W/C ratio units,
W/C = 30/35 (in liters).
= 0.86.
Option "D" is the correct answer.

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.

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

Cement 1 bag weight 50 kg.
Water is 30 liter.
W(Water)/C(Cement) = 30/50 = 0.6.
Option 'C' is the correct answer.
Water is 30 liter.
W(Water)/C(Cement) = 30/50 = 0.6.
Option 'C' is the correct answer.

Water cement ratio is based on Weight Ratio. So we would find the 30 litres = 30 kg and that's why the answer is C.

w/c ratio should be in units of weights only.
Hence, 30lit water=30kg of water.
50kg cement.
W/c = 30/50 = 0.6.
Hence, 30lit water=30kg of water.
50kg cement.
W/c = 30/50 = 0.6.

The water cement ratio is taken as ( volume of water/weight of cement).
So, the answer given is correct.
So, the answer given is correct.

Wt of 30l water = density * Volume = 1000 kg/m3 * 30*10^-3 m3 = 30 kg.
W/c = 30/50 = 0.6.
W/c = 30/50 = 0.6.
