let the revenues from car sales for 1996 = x
let the revenues from truck sales for 1996 = y
in 1997
let the revenues from car sales = 0.89x
let the revenues from truck sales= 1.07y

so total rev for 1997= 0.89x +1.07y-------1

given-total revenues from car sales and truck sales in 1997 were up 1 percent from 1996
so total rev for 1997= 1.01(x +y)----------2

solving 1 and 2

RATIO = 1 : 2

IMO A
