Question

Q4. The mean of 6 numbers is 16. With removal of a number the mean of remaining numbers is
17. Find the number removed.​

Answer 1

Answer:

11

Step-by-step explanation:

Mean of 6 numbers = 16.

=> Sum of 6 numbers = 16 * 6 = 96.

With a number removed, the number of numbers = 6 - 1 = 5.

Mean of 5 numbers = 17.

=> Sum of 7 numbers = 85.

So the number removed = 96 - 85 = 11.
