Coin Toss
I made a machine which can toss coin at exactly same force every time.
I observed that in each toss the coin completes 25 rotation taking total time of 3706 milliseconds.
Coin looses its force at 4% after completing each rotation.
What time (in milliseconds) is taken by coin to complete first rotation..??

Assume that first rotation completes in 100 milliseconds.
When coin completes second rotation it will loose its 4% force and time will increase by 4 milliseconds completing second rotation in 104 seconds. and so on.
So theoretically after 25 rotations you will require 4164 milliseconds.
Compare assumption with actual total time.
i.e. for total 4164 milliseconds first rotation completed in 100 milliseconds then how many milliseconds will it take when total time is 3706 milliseconds.
Answer will be 89 Milliseconds.
