BMI index

Calculate BMI (body mass index, an index indicating obesity, overweight, normal weight, underweight) man weighing m = 102 kg and height h = 159 cm. The index is calculated according to the equation (formula):

$BMI=\frac{m}{h^2}$

With the BMI index, it is possible to compare people of different heights in the following categories:

BMI	Category
bellow 18,5	Underweight
18,5 - 24,9	Normal weight
25,0 - 9,9	Overweight
30,0 - 34,9	Obesity 1st grade
35 - 39,9	Obesity 2nd grade
above 40	Obesity 3rd grade

Correct answer:

BMI =  40.3

Step-by-step explanation:

$$\begin{gathered} h=159\text{cm}\to \text{m}=159:100\text{m}=1.59\text{m} \\ m=102\text{kg} \\ BMI=\frac{m}{h^2}=\frac{102}{1.59^2}=40.3 \end{gathered}$$
