It is implied that the servant was the one who caused the profit. Alternate translation: "Lord, I used your mina to make a profit of five more minas" (See: [[rc://en/ta/man/translate/figs-explicit]])
A mina was 600 grams, probably of silver. Each mina was equal to 100 days' wages, what people would be paid for about four months' work. See how you translated this in [Luke 19:13](../19/13.md). (See: [[rc://en/ta/man/translate/translate-bweight]])
