Answer: Maggie is 7 years old.
Step-by-step explanation:
Maggie = x years old
Maggie’s brother = 4x - 3 years old
x + 4x - 3 = 32
5x -3 = 32
5x = 35
x = 7
Use present value equation.
If present value of annuity equals 400,000, then you are indifferent.

where v = 1/(1+r) and A = annual payment = 800,000/20 = 40,000
PV = 400,000
After subbing in the numbers, the equation is:

Therefore at interest rate of about 7.75% you are indifferent.
