The ratio of the first and second class fares between two railway stations is 4 : 1 and that of the number of passengers travelling by first and second classes is 1 : 40. If on a day Rs. 1100 are collected as total fare, the amount collected from the first class passengers is = ?
A. Rs. 315
B. Rs. 275
C. Rs. 137.50
D. Rs. 100
Answer: Option D
Solution(By Examveda Team)
| 1st | : | 2nd | |
| Fare | 4x | : | x |
| Passengers | 1 | : | 40 |
Total fare = 4x : 40x = 44x
⇒ 44x = 1100
⇒ x = $$\frac{1100}{44}$$ = 25
∴ Fare = 1st class amount received per day
⇒ 4x = 4 × 25
⇒ 4x = 100
