Question

Can you tell me house number of 5 friends if
Mean = 6
Median = 7
Mode = 3
Of their house numbers.​

Answer 1

The house number are 3,3,7,8,9

Step-by-step explanation:

From the definition of mean we know that

Mean = sum of values / total number of values

Since, it is given that total friends are 5

Sum of house number = 6 x 5 = 30

Now, we know median is the middle value

sum of four houses = 30-7 = 23

We also know that mode is the number that is repeated most in the given values. Since, we know that one middle number is 7, then considering mode "3" we will get

23-3-3 = 17

Now, we have three number 3,3,7

Now the remaining number should be greater than 7 whose sum should be equal to 17. Thus,

8 + 9 = 17

Hence, the house number are 3,3,7,8,9
