It is very simple water percentage is 25 If any guy doubt it than any other contact me than I will prove it.

If we take 1500 gm of water then.
Weight of water=400% of weight of cement. Would it be of standard consistency?
Prof. @Rajayogan and Mr @Nitin are right.

Percentage of water = 1875-1500/1500 = 25%.

Simply p of water = (375/1500)*100 = 25%.

Percentage of water = wt of cement/weight of water = (1875-1500)/[1500]*100 = 25%.

weight of cement - weight of water/weight of tare wt*100
a - b/b*100.
So, 1875-1500 = 375/1500*100 = 25%.
a - b/b*100.
So, 1875-1500 = 375/1500*100 = 25%.

If we will add 1500 gm of water in 375 gm of cement then will it be a cement paste or cement solution ? I am satisfied with Prof. P. Rajayogan's comment.

@B.Arun Kumar, @Malavika.
As per the question,
The percentage of water = (weight of water/ weight of whole mixture)*100.
= (1500/1875)*100.

@Malavika.
As normal consistency test is conducted by mixing water and cement. The value 1875 is for both cement and water. When we subtract water value i.e. 1500g from whole 1875 (cement water paste) we get the weight of the cement.

Weight of water = 1500g.
Weight of cement paste = 1875g.
Weight of cement = 1875-1500.
= 375g.
% of water = wt.of cement/wt.of water.
= (375/1500)*100.
= 25%.
