0.6 means 60 liter water per 100 kg cement as 1 bag of cement contains 50 kg of cement.
So 60/2 = 30 liter water required per bag of cement.
So 60/2 = 30 liter water required per bag of cement.

See 30%of cement means 0.3*50 kg = 15 kg.
5% of fine aggregate 0.05*150 = 7.5 kg.
0.6*(15+7.5) = 13.5 kg+14 kg.
5% of fine aggregate 0.05*150 = 7.5 kg.
0.6*(15+7.5) = 13.5 kg+14 kg.

Water required = (5% of aggregate + 30% of cement)*w/c.
Cement per bag = 50 kg.
Aggregate = 50*3 = 150 kg.
5% of aggregate = 7.5 kg.
30% of cement= 15 kg.
Water required = (15+7.5)*0.6 = 13.5 kg which may be approximately 14 kg.
Cement per bag = 50 kg.
Aggregate = 50*3 = 150 kg.

Why we take aggregate 150 kg?
3 times of cement? Explain please?

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

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

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.
