Question

The ratio of first class and second class fares between two stations is $6:4$ and the number of passengers travelling by first class and second class is $1:15$. If total fare collected in one day is Rs.$2200$, then the amount collected from first class passengers is

Answer 1

Ratio of first and second class fares $=6:4$
Ratio of number of passengers $=1:15$
Ratio of the amount collected from each class is
$\frac{6\times 1}{4\times 15}=\frac{1}{10}$
So, the amount collected from first class is $\frac{1}{10+1}\times 2200=200$
