Between two railway staions the fare of 1^(st), 2^(nd) and 3^(rd) class are in the ratio 8:6:3. But later on the fare of 1^(st) and 2^(nd) class is decreased by (1)/(6) and (1)/(12) spectively. In one year the no. of passengers of 1, 2nd and 3rd class are in the ratio for 4:9:24. If total tickets amounting Rs 355600 are sold then find the fare of all 3rd class.

The sum of three numbers is 57 and the ratio of 1st and 2nd is 3 : 7 and 2nd to 3rd is 7:9 The second number is-

Railway fares of 1st, 2nd and 3rd class between two stations were in the ratio of 8 6 : 3. The fares of 1st and 2nd class were subsequently reduced by 1/6a n d1/(12) respectively. If during a year the ratio 12 between the passengers of 1st, 2nd and 3rd classes was 9 :12 : 26 and the total amount collected by the sale of tickets was Rs, 1088, then find the collection from the passengers of 1st class.
