From above given table ,we can see that
in 1992 , total sales = 380.1
gross profit = 149.9
and net profit = 38.9
in 1993 , total sales = 439.7
gross profit = 160.5
and net profit = 50.3
in 1994 , total sales = 485.9
gross profit = 203.3
and net profit = 65.8
Hence 1993 and 1994 both years show increase in all the categories simultaneously, that is total sales, gross profit and net profit as compared to the previous year .
