Given: Ratio of Democrats to Republicans in a certain state legislature = 5:7.
Legislature has 156 members.
Democrats + Republicans = 12x = 156.
x = 13.
Democrats = 65, Republicans = 91.
Difference = 91-65 = 26.
Answer is B.

D/R = 5/7, so 12*x= 156, x= 156/12 = 13
R-D= 2*x= 2*13= 26.
So, I think B.
R-D= 2*x= 2*13= 26.
So, I think B.
