50/1440(density) * 1000 = 34.722 = 35.

It depends on water/cement ratio.

Answer is correct but it should be 35 liter not 35 kg.

@All.
This Question had been asked SSC(JE) and in that key the answer is 28.
Please tell me, which is the correct answer.

M10:- 34 ltr
M15:- 32
M20:- 30
M25:- 28
M15:- 32
M20:- 30
M25:- 28

The unit is wrong. It should be 35 lit water is required for 1 bag cement where as 22.5 kg water is required for 1 bag cement.
1 m^3 = 1000 lit.
Then find 0.0347 m^3= ? lit.
Ans will be 34.7 lit = 35 lit.
1 m^3 = 1000 lit.
Then find 0.0347 m^3= ? lit.
Ans will be 34.7 lit = 35 lit.

In general:-
Grade minimum w/c water required(lit/bag)
M10 -------> 0.6. ------- 34 (30+4 lit extra)
M15 -------> 0.6 ------- 32 (30+2 lit extra)
M20 -------> 0.55 ------- 30 (28+2.")
M25 -------> 0.5 ------- 27 (25+2.".)
M30/35 -------> 0.45 ------- 25 (23+2.".)
M30 -------> 0.4 ------- 22 (20+2. ".)
Minmum -------> 0.38 ------- 21 (19+2. ".)

W/c ratio is 0.5 -0.7 acc to code.
35/50= 0.7.
35/50= 0.7.

Cement 500= 0.35 m3 (50 kg cement =0.035 m3 cement)
Water Req for cement 38 %
= 0.35 * 38/woo
= 0.133 m3 Water
From Water Density.
1000 kg/m3 = (kg/0.133 m3)
Water = 133 kg.

Simple, the unit should be in litres not kg so the answer is correct, only it should be in litres.
