What in earth, the percentage of water = wt. of cement/wt. of water.
% of water would be (wt. of water/wt. of paste)*100.
% of water would be (wt. of water/wt. of paste)*100.

1500/1875 = 80% is the right answer.

As stated in question 1500 g of water and paste is 1875 then simply we get (weight of water/water+cement)*100 = (1500/1875)*100 = 80%.

Weight of cement = 1875-1500 = 375.
Weight of water = 1500.
w/c = 375/1500*100 = 25%.
Weight of water = 1500.
w/c = 375/1500*100 = 25%.

As we know the formula for water content = wt. of water/wt. solid.
Similarly here, % of water = (wt. of water/wt. of cement) x 100.
So, the data given I question is wrong, wt. of water should be 375 g, and wt of cement paste is 1875 g.
Similarly here, % of water = (wt. of water/wt. of cement) x 100.
So, the data given I question is wrong, wt. of water should be 375 g, and wt of cement paste is 1875 g.

Sir I can't understand why the weight of water is taken (1875-1500) = 375 gm?
Here as per question the wt of water = 1500 gm.
Wt of cement = 375 gm.
And we know that % of water = (WT OF WATER/WT OF CEMENT)*100.
Here as per question the wt of water = 1500 gm.
Wt of cement = 375 gm.
And we know that % of water = (WT OF WATER/WT OF CEMENT)*100.

Wt of cement = 1875-1500 = 375.
Wt of water = 1500.
% of water required = 375/1500*100 = 25% answer.
Wt of water = 1500.
% of water required = 375/1500*100 = 25% answer.

Normal consistency is the ratio of w/c, hence in the question weight of cement is 1500 and weight of water is 1875-1500 = 375.
The question it self is wrong. By understanding the concept we can calculate consistency = 375/1500 x 100 = 25%.

Is this o/o of water constant or what I want to know?

I agree with my colleagues that the question is wrong.
The water weight should be 375 gram.
The water weight should be 375 gram.
