  amount of lilypads doubles every minute, how long will it take for the pond to be 25% covered?

Interview Answer

you can back track - in 60 mins the pool will be filled completely.. therefore, in 59 mins pool will be half filled (50% filled) (lillypads double every min) and it will be 25% filled in 58 mins
