64.99 rounded to the nearest tenth

The above answer is absolute rubbish.

The geometric mean is sqrt(125*5) = sqrt(625) = 25

As it happens, the arithmetic mean is (125 + 5)/2 = 130/2 which is exactly 65. That is nearly the same as the answer given although I cannot understand why it required rounding. Furthermore, 64.99 is a number rounded to the nearest hundredth, not the nearest tenth!
