In one hill station train, there are three categories of seats. The seats are numbered from 1 to 50 in the first class, 51 to 150 in the second class, and 151 to 300 in the third class. Every December, the seat occupancy was 30% in the first class, 50% in the second class, and 100% in the third class. If the per seat charges are Rs 2,000, Rs 1,000, and Rs 500 in first class, second class, and third class respectively, then the income ratio per category in December month is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 6 : 10 : 15.
Calculations:
Total seats in first class = 50
Total seats in second class = 100
Total seats in third class = 150
Seat occupancy in first class = 30% of 50 = 15
Seat occupancy in Second class = 50% of 100 = 50
Seat occupancy in third class = 100% of 150 = 150
The per-seat charges are Rs 2,000, Rs 1,000, and Rs 500 in first class, second class, and third class respectively,
The income ratio per category in December month = 15 × 2000 : 50 × 1000 : 150 × 500
= 30 : 50 : 75
= 6 : 10 : 15
