Step-by-step explanation:
Here Initial amount = $10,00,000
Nominal Interest Rate = 9.2%
inflation Rate = 5%
Real Interest Rate = 4%
in question it was asked to give in real then we will use the real discount rate to know annual spent amount
Present Value = PMT×PVIFA ( at 4% and 20 years)
Therefore, PMT = Present Value of Cash / PVIFA ( at 4% and 20 years)
= 1000000 / 13.5903
= $73581.75
Where, PMT = Annual Spent Amount
PVIFA = Present Value interest Factor Annuity
