Ticks mock 2 Q2 Autocrat

Dera Sir

I have never understood ticks properly.

Anyway, in this question, the reason for the 3/12 is the interest rate future being the 3 month thingy? In other words would not apply to forex future?

Now, the tick value is 12.50….but I get 1250 which i know is wrong. I am taking the 2 decimal places after the future, eg. 95.29….the .29 being .10 and saying 500000 x 3/12x.100?
Please help clear this up
