No it is wrong.
The % of Water= wt of cement/wt of water *100.
The % of Water= wt of cement/wt of water *100.

Question should be like this if 1500 g of cement is required to have a cement paste 1875 g of normal consistency, the percentage of water is,
Then,
Weight of cement = 1500g.
Weight of cement paste = 1875g.
Weight of water = 1875-1500.
= 375g.
% of water = wt.of water/wt.of cement.
= (375/1500)*100.
= 25%.
I think this is understandable.

According to question 400%.
%of wt =wt of water/wt of cement.
Hence. % of wt =1500/375,
=400%.
This answer only according to question.
But original. (375/1500 )100 =25%.
%of wt =wt of water/wt of cement.
Hence. % of wt =1500/375,
=400%.
This answer only according to question.
But original. (375/1500 )100 =25%.

It's approximately 40%.
if we take 1500g water and 1875g cement then it will be 3375g cement paste so in this water/cement ratio will also be 0.44 and percentage of water is also 44%.
So, here option D is correct.

Actually in the question, in place of 'water', it should have been 'cement'. In that case:
Percentage of water will be = (wt of water/wt of cement)*100.
= (1875-1500)*100.
= 25%
Percentage of water will be = (wt of water/wt of cement)*100.
= (1875-1500)*100.
= 25%

Cement paste= water +cement = 1875g,
Amount of water =1500g,
%Water = (1875-1500)/1500 = 25%.
Amount of water =1500g,
%Water = (1875-1500)/1500 = 25%.

I also agree with your concept @P. Rajayogan.

@Farid.
You're right It's 400%.
Hence For Possible For Cement Paste.
Question Should be 1500gm Cement for 25%.

If 1500 g of water is required to have a cement paste 1875 g of normal consistency, the percentage of water is,
According to the question.
Cement paste=1875.
Water=1500.
Cement =1875-1500=375.
Now if we want to know the percentage of cement then=(wt of cement/wt of water) *100
=375/1500*100=25%.
And if want to know the percentage of water then =wt of water/wt of cement *100
=1500/375*100 = 400%.
