the ratio between the number of passengers travelling by i and ii class between the two railway stations is 1 : 50 , whereas the ratio of i and ii class fares between the same stations is 3 : 1 . if on a particular day rs . 1,325 were collected from the passengers travelling between these stations , then what was the amount collected from the ii class passengers ?
let x be the number of passengers and y be the fare taken from passengers . 3 xy + 50 xy = 1325 = > xy = 25 amount collected from ii class passengers = 25 × 50 = rs . 1250 . answer : d
multiply(multiply(50, 1), divide(add(add(add(multiply(const_10, const_100), multiply(const_3, const_100)), multiply(const_2, const_10)), add(const_2, const_3)), add(multiply(1, 3), multiply(50, 1))))
