Guys, 35 ltr is the volume of 1 bag of cement.
The water cement ratio is calculated by considering the weight of both materials.
So the weight of 1 cement bag is 50kg.
And weight of water is 30 litre equal to 30kg.

Ratio will be 30/50 = 0.6

Hi, The Correct answers is 0.6.

Water cement ratio = weight of water/ weight of cement.

The weight of 1-litre water is 1 kg.
So, 30 liter = 30 kg.
Weight of 1 bag cement (volume = 35 liter) is 50kg.

Therefore, W/c ratio = 30/50 = 0.6.

C is the correct answer. I agree.

SAFEE said:   9 years ago
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.

Only option C is correct, because normal range wc ratio is 0.4 to 0.6.

Mudasir said:   9 years ago
Can anybody will confirm me what is the correct answer. 0.6 or 0.86?

I read book, some are saying water cement ratio is measure of wt of water/ wt of cement, and some are saying wt of cement/ volume of cement.

So, if anybody knows please post it.

C is the correct answer.

I agree with the given answer.

Anil kumar said:   8 years ago
The water cement ratio is taken as ( volume of water/weight of cement).
So, the answer given is correct.

Sudhakar said:   8 years ago
w/c ratio should be in units of weights only.
Hence, 30lit water=30kg of water.
50kg cement.
W/c = 30/50 = 0.6.

Hir said:   8 years ago
1lit = 1kg so w/c ratio is;

W/c = 30/50 = 60.
