Answer 1

Answer:

5.5%

Explanation:

This is an Annuity Due question. In an annuity due, recurring payments occur at the beginning of the yearIt is asking for the RATE. Using a financial calculator(on BEG mode), input the following;

Duration; N = 25

Recurring payment; PMT = 23.6

Present value ; PV = -334

One-time future cashflow; FV = 0

Then compute the interest rate; CPT I/Y = 5.499%

Therefore, the lottery commission is using about 5.5% interest rate.
