I dint get last two steps. Y are you multiplying toff*5 ?
Whats the correct formula ? anyone please explain ?

Solution:
Ton+Toff=T
f=(1/RC)=6090...
1/f=Toff
Toff*5=82microsec.
Ton+Toff=T
f=(1/RC)=6090...
1/f=Toff
Toff*5=82microsec.

T=R*C
T=82K*200PF=0.0000164
The capacitor will take 5 time constant for fully discharge.
So, 0.0000164*5=0.000082 Sec is equal to 82 µs.
T=82K*200PF=0.0000164
The capacitor will take 5 time constant for fully discharge.
So, 0.0000164*5=0.000082 Sec is equal to 82 µs.

How get time constant = 5?

5 is the Toff period which will be obtained by .0000164/32.8 = 5.
5 times the RC constant = Charging time.
5 times the RC constant = Charging time.
