1,040

Explanation:

The Herfindahl index is an index that is used to measure the size of firms in relation to the industry and it also shows the level of competition among the firms in the industry. The Herfindahl index is also known as Herfindahl-Hirschman Index (HHI).

The Herfindahl index is calculated by summing the square of the market share of all firms in the industry. For this question, it can be calculated as follows:

Herfindahl index = (12^2 * 5) + (8^2 * 5) = 720 + 320 = 1,040.
