sales for 11 months = 11*x/4, where x - sales for december.
total sales = x + 11*x/4 = 15x/4 -> x/total sales = 4/15 -> B

Perfect # pickin problem. Just pick a number. $100 a month for Jan--> Nov and $400 for Dec. 400/1500 = 4/15 B.

4/15, but i for some reason took a long time to get this. i realized i didnt read the question properly the first time around. anyways:

d = 4*(x/11) where d=december sales and x=sales total for jan-nov

we are ultimately after d/x+d

so, rearranging the first eqn, we get x=11d/4. substitute this into number two:

d/(11d/4 + d) = d/((11d+4d)/4) = d/(15d/4) = 4d/15d = 4/15

x is the average monthy sales. So Dec=4x and the other 11 months are 11x

So 4x+11x = total. 4x/15x --> 4/15

B
