In an experiment of simple pendulum, time period measured was `50s` for `25` vibrations when the length of the simple pendulum was taken to be `100cm`. If the lest count of stop watch is `0.1s` and that of metre scale is `0.1 cm`, calculate the maximum possible percentage error in the measurement of value of `g`.
