The weights and heights of students A, B, C, D, and E are given below. BMI = (Weight × 10000) / (Height²). What is the approximate ratio of the BMI of A and B?

13: 18
18: 13
39: 37
37: 39

Correct answer: 39: 37

Solution

BMI is proportional to weight divided by the square of height. For A and B, the ratio is \(\frac{90/180^2}{70/170^2}\), which simplifies approximately to 39:37. Hence, the correct answer is 39:37.
