Question

a, b, c and d are four integers. Their mean is 8 Their mode is 7 Their median is 7.5 (a) Find the value of the largest of the four integers.

Answer 1

7, 7, 8, 10 are the four integers

Explanation:

7 + 7 + 8 + 10 = 14 + 18 = 32/4 (to find mean)

=8

Mode means a number that occurs the most often, so 7 will be the answer

Median is the middle number, and that will be 7 and 8. To find median, you add up 7 and 8 together and divide the number by 2 to find the average, and that will be 7.5
