ratio of wheat bran to the whole mixture is 6/(10+6+2+2)
therefore, wheat bran in a mixture of 15 tons = (6/20)*15 = 9/2
So, its D

Wheat bran 6x

D. 9/2
E. 15/2

We can create the equation:

10x + 6x + 2x + 2x = 15

20x = 15

x = 15/20 = 3/4

So there are 3/4 x 6 = 18/4 = 9/2 tons of wheat bran in the mixture.
