### SOLUTIONS

1.

(d) Let the first class fare is 4x and second class fare is x Rs.Let the no of passengers travelling by first class is y and by second class is 40y.

total fare of first class=4xy

total fare of second class=40xy

4xy+40xy=1100

xy=25

so amount collected by first class passengers=4xy=4*25=100
