Answer :
Equity is the ownership of any asset after any liabilities associated with the asset are cleared. For example, if you own a car worth $25,000, but you owe $10,000 on that vehicle, the car represents $15,000 equity. It is the value or interest of the most junior class of investors in assets.
Equity is anything that is invested in the company by its owner or the sum of the total assets minus the sum of the total liabilities of the company. E.g., Common stock, additional paid-in capital, preferred stock, retained earnings and the accumulated other comprehensive income.
