Question

A person consumes 2000 calories per day and burn 2100 calories. How many days will it take this person to lose one pound?

a) 7
b) 14
c) 35
d) 42

Answer 1

c) 35

Step-by-step explanation:

Given that a person consumes 2000 calories in a day.

Such a person then later burns 2100 calories per day.

It means that the number of calories being burnt = 2100 - 2000 = 100 calories per day

Recall that:

`1\ pound \ of \ fat \ = \ 3500 \ cal.`

Then

For the person to lose one pound of fat, then it will take him;

3500 calories/100 calories = 35 days
