Add up all the numbers: 632
There are 12 numbers, so the mean is 52.666

Now, you want to remove one value so that the remaining 11 have a mean of 56.09.

Well, 11*56.09 = 617

So, if you remove one of the 15's, the remaining 11 numbers add up to 617, giving the desired mean.

Steve, why is your answer 617? Isn't 11 x 56.09 = 161.99? Why would you round it?
