Answer:
25 years
Step-by-step explanation:
We first set BA II Plus calculator : C/Y = 2, P/Y = 2
Then, I/Y = 10, PMT= -45(1000*9%/2), FV= -1100, PV=918
CPT No of years = N(I/Y, PMT, -FV, PV) (Semi annual period)
CPT No of years = 49.35 (Semi annual period)
CPT No of years = 49.35/2
CPT No of years = 24.68
CPT No of years = 25 years
