Please, reveal the answer

70-80

The question is inaccurate in context.

It should say "what is the normal heart rate in a human".

The heart beat at rest should be 75 to 90, it is considered normal.

Now that number is for when the person is at rest, for different activities heart beats are supposed to be high / low and still be considered normal.
