Select 115 bpm as your answer	115 bpm
Select 220 bpm as your answer	220 bpm
Select 200 bpm as your answer	200 bpm
Select 150 bpm as your answer	150 bpm

Answer 1

To calculate John"s maximum heart rate , we have to subtract his age from 220.

The age is not mentioned in the question,but we can find the answer by eliminating the options.

A-- 115 bpm

So age has to be = 220-115 = 105 years

Not possible.

B-- 220 bpm

Age = 0 years

Not possible

C-- 200 bpm

Age = 220-200=20 years

D-- 150 bpm

Age = 220-150= 70 years

Seeing the stroke volume of 75 ml (105-30=75 ml), option C (20 years ) is more likely.

So answer is C.
