1cubic metre of concrete has a weight of 2400 kg 15 of the concrete is water the rest of the concrete are cement, sandand stone the weight of these ingredients are in the ratio 1: 2: 5 work ouyt the weight of cement, sand and stone in 1 cubic metre of cement

Cement = 255 kg,

Sand = 510 kg,

Stone = 1275 kg.

Step-by-step explanation:

We have been given that 1 cubic meter of concrete has a weight of 2400 kg and 15% of the concrete is water. The rest of are cement, sand and stone.

Let us find 15% of 2400.

The amount of cement, sand and stone will be: .

We are also told that the weight of cement, sand and stone are in the ratio 1:2:5.

We can represent this information in an equation as:

Therefore, the weight of cement in 1 cubic meter of concrete is 255 kg.

Therefore, the weight of sand in 1 cubic meter of concrete is 510 kg.

Therefore, the weight of stone in 1 cubic meter of concrete is 1275 kg.

Weight of cement Kg

Weight of sand Kg

Weight of Stone Kg

Step-by-step explanation:

Given -

The total weight of concrete Kg

Weight of concrete Kg

The weight of cement, sand and stone is equal to

Kg

Let be the weight of cement,

Then weight of sand is

Weight of stone is

On solving the above equation, we get -

Thus,

Weight of cement Kg

Weight of sand Kg

Weight of Stone Kg
