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:

Determine the BMI category of Person A.

Calculate the value of $X$ for Person B. Use the equation:

\text{BMI} = \frac{\text{body mass}}{\text{height}^2}

Give your answer to 3 significant figures.
