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%.

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

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%

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%.

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.

Nitin said:   1 decade ago
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.

@Malavika.

The water cement ratio should not increase or should not exceed 50% weight of cement. The question shall be recapitulated as sir has said.

Normal consistency of water (%) = (wt.of water/wt .of cement) * 100,
Then given

wt .of water : 1500.
wt.of cement : 1875.
= (1500/1875) * 100 = 80%.

@B.Arun Kumar, @Malavika.

As per the question,

The percentage of water = (weight of water/ weight of whole mixture)*100.

= (1500/1875)*100.
