4. Your rich uncle has just offered you to make you wealthy! For every amount you save in an insured bank account during the next 10 years, he will give you the total amount (excluding interest) that you saved to match it.

If you desire a total of P1,00,000 10 years from now, what effective interest rate would you have to earn on your insured bank account to make your goal possible?
