Question

The mean of 6 numbers is 12. The numbers are in the ratio 1 : 1 : 1 : 1 : 2 : 3. Find the median.

Answer 1

8

Explanation:

n = 6

mean = 12

Therefore, sum of numbers = 12 x 6 = 72

Using ratio : 1 + 1 + 1 + 1 + 2 + 3 = 9

Therefore 72 ÷ 9 = 8

Therefore, mulitply each number in ratio by 8 to find the numbers.

The numbers are: 8, 8, 8, 8, 16, 24

So the median is 8
