I'm probably too late with this, but I came across the equation that applies right before reading the question so here goes:
P1 = ((d1)^3/(d1^3+d2^3+d3^3....)) x Poverall
So for this example
Pforpier1and5 = (3^3/(3^3+4^3+4^3+4^3+3^3)) x 10000# = 1097.6
Pforpiers2-4 = (4^3/(3^3+4^3+4^3+4^3+3^3)) x 10000# = 2601.6
As Mike-SE pointed out, these should sum to 10000, and they do, but now the problem is that the correct answer doesn't seem to be one of your possible choices...?
