The ratio of the first and second class fares between two stations is 3 : 1 and that of the number of passengers travelling between the two stations by the first and the second class is 1 : 50. If in a day, Rs. 1, 325 are collected from the passengers travelling between the two stations, then the amount collected from the second class from the second class passengers is  Choose the most appropriate option:
A) 1,250
B) 1,000
C) 850
D) 750
E) 350
Explanation:   Let the fares be 3 x and x respectively for the first and second class.   Suppose in a day passengers travelling between the two stations be 1 and 50.   Then by given condition, 3 x × 1+x × 50=1,325 =&gt; x=25   The amount collected from second class = 25×50 = Rs. 1250   1,250nswer: 1,250
