Question
Following are the car parking charges near a railway station upto
| 4 hours | ₹60 |
| 8 hours | ₹100 |
| 12 hours | ₹140 |
| 24 hours | ₹180 |
Check if the parking charges are in direct proportion to the parking time.
Solution
| Parking time (in hours) |
Parking charges (in ₹) |
Proportion |
| 4 | 60 | `4/60= 1/15` |
| 8 | 100 | `8/100 = 2/25` |
| 12 | 140 | `12/140 = 3/35` |
| 24 | 180 | `24/180 = 2/15` |
Since, `1/15 ne 2/25 ne3/35 ne 2/15`
∴ The parking timing is not in direct proportion to parking charges.
