Well prof is right.
While wt.of cement/wt of water will give ratio not %.

0.85*consistency*wt.of cement = wt.of water.

Given data:
Weight of cement = 1875gm.
Weight of water = 1500gm.
Solution:
Weight of cement = 1875-1500 = 375gm.
% of water = (Weight of cement/Weight of water)*100 = (1875-1500/1500)*100 = 25%.
Weight of cement = 1875gm.
Weight of water = 1500gm.
Solution:
Weight of cement = 1875-1500 = 375gm.
% of water = (Weight of cement/Weight of water)*100 = (1875-1500/1500)*100 = 25%.

I am agree with Prof.P. Rajayogan.

My question for the participants of this discussion forum is that where is the formula for the percentage water as weight of cement divided by weight of water?
I agree with Prof. P. Rajayogan. Thank you Prof. I have the long time confusion for this question. I am also thinking so but I am not getting single one to report this question like that.

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

According to this question.
Weight of water = 1500 g.
Weight of cement paste = 1875 g.
Percentage age of water = (Weight of water/Weight of paste)x100%.
i.e 5 = (1500/1875)x100.
=> 80%.
Weight of water = 1500 g.
Weight of cement paste = 1875 g.
Percentage age of water = (Weight of water/Weight of paste)x100%.
i.e 5 = (1500/1875)x100.
=> 80%.

Weight of cement = 1875-1500 = 375.
So % of water = 375/wt of water.
= 375/1500*100.
= 25%.
So % of water = 375/wt of water.
= 375/1500*100.
= 25%.

Wt. of water = 1500 gm.
Wt. of cement = 1875-1500 = 375 gm.
w/c = 1500/375 = 40%.
This means each 1 gm of cement needs 4 gms of water.
Wt. of cement = 1875-1500 = 375 gm.
w/c = 1500/375 = 40%.
This means each 1 gm of cement needs 4 gms of water.

But, weight of water is 1500g.
So % = Weight of water/Weight of paste*100.
= 1500/1875*100 = 80%.
So % = Weight of water/Weight of paste*100.
= 1500/1875*100 = 80%.
