Using the net worth method, calculate an individual's income from unknown sources. The following information is available:Increase in net worth $100,000, Known income $80,000, Salary $60,000

1. $0

2. $10,000

3. $20,000

4. $40,000

3. $20,000

Explanation:

Given,

Net worth increase = $100,000,

Since, Net worth increase + living expenses = income,

If there are no living expenses,

Net worth increase = income

Thus, income = $100,000,

Now, income = income from unknown sources + income from known sources,

We have, income from known sources = $80,000,

By substituting the values,

$100,000 = income from unknown sources + $80,000,

⇒ Income from unknown sources = $100,000 - $80,000 = $20,000

Hence, option 3 is correct.
