Question 11

Easy

The Body Mass Index (BMI) is a measure used to assess whether a person has a healthy body mass for their height.

Table 1 shows information about two people, Person A and Person B.

Person	Body mass in kg	Height in m	BMI in $kg/m2\text{kg/m}^2$
Person A	54	1.62	20.6
Person B	88	1.68	$X$

Table 2 shows the standard BMI categories for adults:

BMI Range ( $kg/m2\text{kg/m}^2$ )	BMI Category
Less than 18.5	Underweight
18.5 to 24.9	Normal
25.0 to 29.9	Overweight
30.0 to 39.9	Obese
40.0 or more	Clinically obese

Determine the BMI category of Person A.

[1]

Calculate the value of $X$ for Person B. Use the equation: $massheight2\text{BMI} = \frac{\text{body mass}}{\text{height}^2}$ Give your answer to 3 significant figures.
