Answers
Given : 4 whole numbers whose median is 18 and range is 3
To find : Numbers
Solution:
Let say four numbers in ascending order are
a b c d
d = a + 3 as range is 3
Median will be = (b + c) /2 = 18
=> b + c = 36
hence b & c can be 18 + 18 or 17 + 19 ( 16 + 20 and further will have range more than 3)
then possible numbers
16 18 18 19
17 18 18 20
15 18 18 18
18 18 18 21
16 17 19 19
17 17 19 20
