Answer 1

Calculation of Coal Consumption

To calculate the amount of coal consumed in January, we need to first determine the total amount of coal remaining after December.

Given: - Total amount of coal delivered: 60 tons - Coal consumed in December: 1/5 of the total amount - Coal consumed in January: 1/2 of the remaining coal

Let's calculate the amount of coal consumed in December and the remaining coal:

1. Coal consumed in December: 1/5 * 60 tons = 12 tons.

To find the remaining coal, we subtract the amount consumed in December from the total amount delivered:

Remaining coal = Total coal - Coal consumed in December Remaining coal = 60 tons - 12 tons = 48 tons.

Now, let's calculate the amount of coal consumed in January:

2. Coal consumed in January: 1/2 * 48 tons = 24 tons.

Therefore, 24 tons of coal were consumed in January.
