Answer 3

Plan of Ore Extraction

To calculate the amount of ore extracted in a day, we can use the information provided. The plan was to extract 1200 tons of ore per day, and the work brigade completed seven-fourths of the plan.

Calculation: - 1200 tons/day * 7/4 = 2100 tons

So, the work brigade extracted 2100 tons of ore in a day.

This calculation is based on the completion of seven-fourths of the plan, resulting in 2100 tons of ore extracted in a day.
