The correct option is B >
Cost of train fare = $ 811
Cost of bus fare = $ 811×23
To compare the two fares, we need to compare the two fractions.
A number when gets multiplied with another number which is less than 1, the product is always less than the original number.
∵23 < 1,
so, 811×23 < 811
∴ Cost of train fare > Cost of bus fare
