Answer: The person lived for 80.66 years.

Explanation:

Heart beat of the person = 73 beat /min

Number of total heart beats = $3.1\times 10^{9}$

Life span of the person : $\frac{\text{Total heart beats of the person}}{\text{Heart beat per minute}}=\frac{3.1\times 10^{9} beats}{73 beat/min}$

1 year =525600 mins

Life span = $0.0424\times 10^{9} min=80.66 years$

The person lived for 80.66 years.
