A certain company that sells only cars and trucks reported that revenues from car sales in 1997 were down 11 percent from 1996 and revenues from truck sales were up 7 percent from 1996. If total revenues from car sales and truck sales in 1997 were up 1 percent from 1996, what is the ratio of revenue from car sales in 1996 to revenue from truck sales in 1996?  Options
A) 1:2
B) 4:5
C) 1:1
D) 3:2
E) 5:3
This is a weighted average question. Average of -11% and +7% is +1%.   Using w1/w2 = (1:22 - 1:2vg)/(1:2vg - 1:21),   we get w1/w2 = (7 - 1)/(1- (-11)) = 6/12   Revenue from Car:Revenue from Trucks = 1:2   1:2NSWER:1:2
