For ratio, 1:3:6 w/c ratio-0.60.
So water required for 1 bag (50 kg) cement is=50*0.60=30 lit.
So water required for 1 bag (50 kg) cement is=50*0.60=30 lit.

Please explain correctly, whether 30 is correct or 14 is correct?
If any then explain how.

1 bag cement concrete work need for water.

Excellent explanation. Thank you all.

W/c ratio means the ratio of the weight of water to the weight of cement so that 0.6 * 50 = 30 kits or kg.

Generally, water cement ratio is taken in between 0.5-0.6.
@Nazim.
w/c= water/cement
0.5= water/1 bag
0.5= water/50kg
water= 25 litres.
@Nazim.
w/c= water/cement
0.5= water/1 bag
0.5= water/50kg
water= 25 litres.

Yeah, that's the Water is required 60% of the cement means if we are considering the 1 bag of 50kg then for water. It will become (60/100) 50 = 30 litres.

Water cement ratio 0.6 means, 50 * 0.6 = 25.

I think the correct answer is 30 kg.

Here we have to know only about the requirement of water for 1-bag of cement.
We know 1bag contain 50 kg cement.
As per w/c ratio its value 0.6 i.e 60 litre pe 100kg cement,
So the density of cement nearly 1440kg/cum,
Density = mass/volume.
So, volume=[mass]/density * 1000,
i.e 50/1440 * 1000,
Ans is 34.7222 which is nearly 35.
Hence 35 kg answer is right.
