It means that in India 50 revolutions are taken by the coil in one second and we know that the current reverses it's direction 2 times in one revolution so in one second the direction of current changes 100 times.

The frequency of revolution is 50 Hz.
Which means that in 1 seconds it does 50 rotations.
We know that electricity generated from an AC generator changes the direction of current in 1/2 revolutions , in 1 revolution the direction of electric current changes 2 times.
In 1 second = 50 revolutions which means that the direction of current is changed 100 times in a second.
Therefore it means that the direction of current changes in 1/100 th second.
