In urban areas, auto rickshaws are amongst the most prevalent modes of transport. The pricing system usually consists of two segments:
  1.  A predetermined fee of \(₹\) \(26\), and
  2. Additional charge of \(₹\) \(7\) per kilometre travelled.
If the total amount paid by a passenger is \(₹\) \(68\), then solve the following queries:

1. Express this situation in the form of a linear equation in two variables.


2. How much will the passengers have to pay on a journey of \(6\) \(km\)?


3. If a standard static charge is applied, what will be the overall charge if the traveller moves by less than \(1\) \(km\)?


4. If the additional charge is increased by \(₹\) \(3\), then how much will the passengers have to pay on a journey of \(6\) \(km\)?
