The image you provided contains three questions related to mathematics. Here’s a transcription of each question:

1. Question 2.2:
   "The winner of a lottery was given the choice of receiving R1 000 000 now or R1 025 000 in two years' time. What is the nominal interest rate per annum, compounded annually, that makes the winner indifferent between the two options?"

2. Question 2.3:
   "A firm is to replace its machine after six years with a new model. What will be the compound interest accumulated if R50 000 is deposited at the end of each year for six years in an account that earns 6% per annum?"

3. Question 2.4:
   "What will be the monthly equivalent of the amount in 2.3?"
