Full text
162. For the purposes of section 160, where a person borrows money in consideration of a promise by him to repay a larger amount and pay interest on the larger amount, the amount borrowed is deemed the larger amount. However, where the amount actually borrowed has been used in part only to earn income from a business or property, the amount so used is deemed the proportion of the larger amount that the amount actually so used is of the amount actually borrowed.
