Direction: 2 ton of cement is used to make 10 ton of hardened concrete having a water cement ratio of 0.45.
One cubic meter of this concrete has a mass of 2.5 ton.
-
Quantity of water used (in kg) is
-
- 90
- 450
- 900
- 945
Correct Option: C
Water: Cementratio is 0.45, i.e. 45/100 = 9/20
Now 2 ton that is 2000 kg of cement would contain 0.9 ton of water, i.e 900 kgs of water.
