Question

7,9,20,3,9. A number is removed from this list and the median and range do not change. What is the number

Answer 1

Answer: 7

Step-by-step explanation: range is highest value-lowest value

So we can take any number other than 20,3

Now for median we know that it is the average of middle term or terms when arranged in order is 3,7,9,9,20

Now we can not remove 9 if we remove than median will change so we have only one option left 7 if we remove it the median remains same
