Number of trucks manufactured by D and F together is what percent of the number of trucks manufactured by G and I together?

220.2 percent

Number of trucks manufactured by D and F together = $\frac{degree}{360°}$ x Total number  

                                                                            = $\frac{196°}{360°}$ x 1800 = 196 x 5 = 980        

Number of trucks manufactured by G and I  together = $\frac{degree}{360°}$ x Total number                                                                           

                                                                             = $\frac{89°}{360°}$ x 1800 = 445

Number of trucks manufactured by D and F is $\frac{980}{445}$ x 100% =  220.2 % of the trucks manufactured by G and I together
