Ex 13.1, 1 Following are the car parking charges near a railway station upto 4 hours Rs 60 8 hours Rs 100 12 hours Rs 140 24 hours Rs 180 Check if the parking charges are in direct proportion to the parking time. We write it in table Checking ratio of (๐ท๐๐๐๐๐๐ ๐๐๐๐)/(๐ท๐๐๐๐๐๐ ๐๐๐๐๐๐๐) 4/60 = 1/15 8/100 = 2/25 12/140 = 3/35 24/180 = 2/15 Since ratio of time & charges is not the same. Parking charges are not in direct proportion to parking time.
