Answer 2

Calculating Percentage of Gravel in Concrete

To calculate the percentage of gravel in the concrete, we can use the following formula:

Percentage of gravel = (Weight of gravel / Total weight of concrete) * 100

Given: - Weight of cement = 800 kg - Weight of sand = 600 kg - Rest is gravel

Let's calculate the percentage of gravel in the concrete using the provided information.

First, we need to find the weight of gravel: Weight of gravel = Total weight of concrete - (Weight of cement + Weight of sand)

Weight of gravel = (Weight of cement + Weight of sand)

Weight of gravel = (800 kg + 600 kg) = 1400 kg

Now, we can calculate the percentage of gravel in the concrete: Percentage of gravel = (1400 kg / (800 kg + 600 kg + 1400 kg)) * 100

Percentage of gravel = (1400 kg / 2800 kg) * 100

Percentage of gravel = 50%

So, 50% of the concrete is made up of gravel.
