Question

A body builder consumed 4,400 calories yesterday. Today, he consumed 3,600 calories.

Answer 1

4400 - 3600 = 800

Decrease = 800 Calories

Original value was 4400 Calories.

Now,

   $\frac{800}{4400}$×$100$

$=\frac{2}{11}$×$100$

$=\frac{200}{11}$×$18.8$%

After Rounding off,

Decrease percentage will be 18 %
