5:7 can be written as 5/7
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5/7 = 1421
(1421*5)/7 = 1015

The language isn't clear; but I believe you are asking for the amount of increase in the fare....
The ratio 5:7 means we can represent the old fare by 5x and the new fare by 7x; the amount of increase in the fare is 7x-5x = 2x.
The new fare, 7x, is rs. 1421:
The amount of increase in the fare is 2x = 2 * rs. 203 = rs. 406.
