The revenue of a railway zone was collected from Online Ticket Sales, Offline Ticket Sales, Freight, and Fines during three financial years: FY 2013-14, FY 2014-15, and FY 2015-16. The total revenue in FY 2013-14 was ₹3500 crore. Fines (₹X crore) made up $\frac{6}{7}$ of the total revenue, and revenue from online ticket sales was $X + 300$ crore. Revenue from freight was 12% more than offline ticket sales.

In FY 2014-15, revenue from online ticket sales increased by ₹25 crore compared to FY 2013-14. Offline ticket sales accounted for 40% of the total revenue in FY 2014-15. Revenue from freight and fines were in the ratio 5:1.

In FY 2015-16, revenue from fines in FY 2013-14 was $\frac{11}{16}$ of that in FY 2015-16. Online ticket sales increased by 50% over FY 2014-15, and offline ticket sales were the average of FY 2013-14 and FY 2014-15. Freight revenue increased steadily by ₹250 crore each year.

Revenue from fines comprised two sources: vendors and passengers. The fines from passengers (₹Y crore) remained the same in FY 2013-14 and FY 2014-15. If the fine from vendors in FY 2013-14 was 55% of that in FY 2014-15, what was the value of Y?
