Answer: 2,550

Explanation;

The Herfindahl-Hirschman Index (HHI) is used to measure market saturation to see the concentration of a market. It ranges from around 0 to 10,000 and is calculated by squaring the market share of every firm in the market and then adding the squares up.

= 40² + 20² + 15² + 15² + 10²

= 1600 + 400 + 225 + 225 + 100

= 2,550
