Given, fares of air conditioned sleeper and ordinary sleeper class are in the ratio 4 : 1.

Let the fares of air conditioned sleeper and ordinary sleeper class be 4a and a.

Also, the number of passengers travelled by air conditioned sleeper and ordinary sleeper classes were in the ratio 3 : 25.

Let the number of passengers be 3b and 25b respectively.

Total collection was Rs. 37000

⇒ 4a × 3b + a × 25b = 37000

⇒ 37ab = 37000

⇒ ab = 1000

Total amount paid by air conditioner sleeper passengers = 4a × 3b = Rs. 12000
