Please explain how he arrived at $10,000 when he had a nonbusiness bad debt of $11,000?

Problem 7-29 (LO. 1) Monty loaned his friend Ned $20,000 three years ago. Ned signed a note and made payments on the loan. Last year, when the remaining balance was $11,000, Ned filed for bankruptcy and notified Monty that he would be unable to pay the balance on the loan. Monty treated the $11,000 as a nonbusiness bad debt. Last year, before considering the tax implications of the nonbusiness bad debt, Monty had capital gains of $9,000 and taxable income of $45,000. During the current year, Ned paid Monty $10,000 in satisfaction of the debt. Determine Monty's tax treatment for the $10,000 received in the current year. The nonbusiness bad debt of $11,000 would have been reported as a short-term capital loss ,and $ 10,000 would be included in Monty's gross income
