1:3:6 is the proportion that he has asked.
Density = Mass/Volume.
Density of concrete = 1400 kg/m3.
Mass of cement = 50 kg (given).
1440 = 50/v, hence v = 0.035 m3.
Water = 0.035*3 = 0.105 m3.
Aggregates = 0.035*6 = 0.21 m3.
Cement:Sand:Aggregates = 0.035:0.105:0.21 (in m3).
Cement:Sand:Aggregates = 35:105:210 (in lts if multiplied above result with 1000 as 1 m3 = 1000 lts).

Volume of one beg cement = 0.035 cum.
Hence sand = 0.035*3 = 0.105 cum.
1 cum = 1000 lt.
So sand = 0.105*1000 = 105 lt.
& Aggregates = 105*2 = 210 lt.
Hence sand = 0.035*3 = 0.105 cum.
1 cum = 1000 lt.
So sand = 0.105*1000 = 105 lt.
& Aggregates = 105*2 = 210 lt.

Guys I am a bit confused here. Isn't it kg and liters are equal? Then why not 50 kg of cement = 50 liters of cement?

1kg = 0.7 liters.
50kg cement - 35liters.
3*50kgsand-150 * .7 = 105liter.
300kg aggregate-300*.7 = 210 liters.
50kg cement - 35liters.
3*50kgsand-150 * .7 = 105liter.
300kg aggregate-300*.7 = 210 liters.

Clear cut solution:
A cement bag contains 35 liters of cement,
35 x 1 : 35 x 3 : 35 x 6.
= 35 : 105 : 210.
A cement bag contains 35 liters of cement,
35 x 1 : 35 x 3 : 35 x 6.
= 35 : 105 : 210.

The Volume of 50kg bag of cement =35 litre,
Therefore;
Sand 35x3=105.
Aggregate 35x6=210.
Therefore;
Sand 35x3=105.
Aggregate 35x6=210.

Density = Mass/Volume.
Weight = Density*Volume*9.81.
Why should we multiply with 9.81?
Weight = Density*Volume*9.81.
Why should we multiply with 9.81?

50 kg of cement - 35 lit volume.
1:3:6
35 lit cement : 105 lit sand : 210 lit c.a.
1:3:6
35 lit cement : 105 lit sand : 210 lit c.a.

@Rohit the density of concrete is 2400 kg/m3. Where did you get 1400 kg/m3?
