1. A bank can lend a client Php 10,000.00 with a simple annual interest rate of 3% to be paid after 3 years. If the same principal amount and future worth are to be strictly transacted but using compounded interest annually to be paid after the same number of years, what should be the interest rate?

2. A loan of Php 2,500 is made for a period of 13 months, from January 1 to January 31 the following year, at an interest rate of 5%, compounded quarterly. What future amount is due at the end of the loan period? 3. You borrowed a certain amount of money to be paid after some years. If the interest rate is 1.2% compounded biannually, when should you pay the amount such that it's only 50% more than the principal amount?
