Arrange the values in ascending order: 13, 22, 31, 38, 47, 69, 73, 82

There are 8 numbers all together.
3/4 of 8 = 6
1/4 of 8 = 2

So we're looking for a number that's greater than 6 of the numbers but less than 2 of the numbers
In other words, we want a number that's greater than 69 but less than 73 like so: 13, 22, 31, 38, 47, 69,| number | 73, 82
71 is one such number.
