Answer:

a) Lower limit range = 119.7 ≈ 120

b) Upper limit range = 136.8 ≈ 137

Step-by-step explanation:

Given:

a) Lower limit range = \frac{\textup{7}}{\textup{10}}\times(220-\textup{Age})

Therefore,

For the given person of age 43 years old

substituting the value of age in the above equation, we get

Lower limit range = \frac{\textup{7}}{\textup{10}}\times(220-\textup{49})

or

Lower limit range = 119.7 ≈ 120 beats per minute

b) The upper limit range = \frac{\textup{4}}{\textup{5}}\times(220-\textup{Age})

Therefore,

For the given person of age 43 years old

substituting the value of age in the above equation, we get

Upper limit range = \frac{\textup{4}}{\textup{5}}\times(220-\textup{49})

or

Upper limit range = \frac{\textup{4}}{\textup{5}}\times(220-\textup{49})

or

Upper limit range = 136.8 ≈ 137 beats per minute
