lets expand n x (2^5) x (6^2) x (7^3) and this can written as = nx (2^5)x(7^3)x(2^2x3^2) now as we can see that 5^2 is completely missing from the expression above so n must atleast have 5^2 and we can also infer from the expression that in order for 3^3 to be factor of the expression we would need...

B = 8.47 + S
B = W - 12.95
B + S + W = 160
Now substitute the information .
B + (B-8.47) + ( B+12.95) = 160
we get B = 51.84, W = 64.79 and S = 43.37
