Answer:
The number of years is about 21 years
Explanation:
A scheme that allows the withdraw fixed amount of money for a number of years is referred to as annuity
The number of years required to exhaust the fund can be determined using the present of annuity formula
PV = A × (1 - ((1+r)^(-n))/n)
where- PV- Present value, A- annual cash flow, n- number of years , r- interest rate
500,000= 50000 × (1- (1.08)^(-n)/0.08
500,000/50,000= (1- (1.08)^(-n)/0.08
10 =(1- (1.08)^(-n)/0.08
n = 21
The number of years is about 21 years
