Given that:

Ton = 2ms.

3*Ton+3*Toff = 20ms.

Then Toff = 8ms.

Duration of complete pulse(T) = 10ms(Ton+Toff).

Then frequency = 1/T = 1/10ms = 100Hz.

How? please explain clearly.

Ton = 2ms(given).
2Toff + 2Ton = 20mS(given).

Hence, Toff = 8mS.
Ton + Toff = 10mS.
then f=1/10mS = 100Hz.

Because the frequency is 1 cycle/time.

When you look at the graph during 20ms of duration it generates two cycles thus we divide 20ms/2 it will become 10ms per cycle thus using f=1/t.

F = 1/10×10^-3.
F = 100Hz.
