Difference in percentage of Heavy Vehicles $=\frac{ Heavy Vehicles sale in 1993 - Heavy Vehicles sale in 1992}{ Heavy Vehicles sale in 1992}$

$ = \frac{3}{72}= 4 % \uparrow $

Difference in percentage of Light Commercial Vehicle $=\frac{ Light Commercial Vehicle sale in 1993 - Light Commercial Vehicle sale in 1992}{Light Commercial Vehicle sale in 1992}$

$ = \frac{14}{79}= 17 % \uparrow $

Difference in percentage of Jeeps $=\frac{ Jeeps sale in 1993 - Jeeps sale in 1992}{Jeeps sale in 1992} = \frac{31}{210}= 14.7 % \uparrow $
