Given set of scores= 124, 856, 331, 227, 963, 338, 259 and 662

We know the formula,

 $\mathrm{Average} \left(\mathrm{A}\right)=\frac{\mathrm{Sum} \mathrm{of} \mathrm{given} \mathrm{values} \left(\mathrm{S}\right)}{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{values} \left(\mathrm{N}\right)}$

 Here,

 Sum of given values(S)

=124+856+331+227+963+338+259+662

= 3760

Total number of values(N)= 8

Substituting these values we get (A),

 $= \frac{3760}{8}=470$

Hence, Option E is correct.
