Answer 2

Calculation of Initial Coal Quantity

To calculate the initial quantity of coal on the warehouse, we can use the information provided. We know that 299.2 tons of coal were unloaded from the warehouse, and after the unloading, 45% of the coal remained on the warehouse.

Let's denote the initial quantity of coal on the warehouse as X.

According to the information given, after unloading 299.2 tons of coal, 45% of the coal remained. This can be expressed as:

0.45X = 299.2

To find the initial quantity of coal, we need to solve this equation for X.

Dividing both sides of the equation by 0.45, we get:

X = 299.2 / 0.45

Calculating this expression, we find:

X ≈ 665.78 tons

Therefore, the initial quantity of coal on the warehouse was approximately 665.78 tons.
