@Salman.
But here told ratio 1:3:6,
Where, 1=Cement, 3=Sand, and 6=Stone.
Therefore Sand + Stone = Aggregate.
So, sum total 3 + 6 = 9. [50x9 = 450Kg].

1:3:6, so we multiply by 1*50 Kg cement and 3 fine aggregate * 50 kg, so.
We get 150 kg fine aggregate.
We get 150 kg fine aggregate.

It's Thumb Rules for deciding the quantity of water in concrete:
(i) Weight of water = 28% of the weight of cement + 4% of the weight of total aggregate.
(ii) Weight of water = 30% of the weight of cement + 5% of the weight of total aggregate.
(i) Weight of water = 28% of the weight of cement + 4% of the weight of total aggregate.
(ii) Weight of water = 30% of the weight of cement + 5% of the weight of total aggregate.

Yeah, I agree with the answer 30.

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.

However, I believe that the density of cement is 1440 Kg/Cum.
Therefore, the volume of a 50 kg cement bag works out to be [ 50/1440 ]*1000 = 34.722 Liters.
Therefore, the volume of a 50 kg cement bag works out to be [ 50/1440 ]*1000 = 34.722 Liters.

Why we are taking 5% of aggregate and 30% of cement?

Water required per bag means:
Cement bag = 50 kg.
W/c ratio = 0.6.
Water = 50 x 0.6.
Hence water = 30 kg.
If we assume water absorption in calculation then water require more than 30 kg.
Cement bag = 50 kg.
W/c ratio = 0.6.
Water = 50 x 0.6.
Hence water = 30 kg.
If we assume water absorption in calculation then water require more than 30 kg.

Its wrong answer is 30 kg.
How can we take water for aggregate if nothing is mentioned?

3 times of cement is fine sand, aggregate is 6 times actually. How you can take aggregate 3 times? Explain please?
