Question

Hayden has three number cards. The

minimum of his three cards is 36, the
range is 41 and the median is 46.
What is the mean of Hayden's three
cards?

Answer 1

Mean = 53.

Explanation:

The median is the middle value so the 3 cards are

36, 46, x where x is to be found.

The range is 41, so:

x - 36 = 41

x = 41 + 36

x = 77.

Therefore, the mean is

(36+46+77) / 3

= 159/3

= 53.
