Ton = 15ms.
Toff = 60ms - 15ms = 45ms.
Duty cycle = Ton/Ton + Toff * 100.
Duty cycle = 25%.

The duty cycle can be found we know total time = 60 ms.
We know ton = 5 ms.

For four cycles ton = 20 ms.
Duty cyle = ton/(ton+toff).
= 20/(20+60).
= 0.25.

For percentage multiply above with 100, the answer would be 25.

Duty cycle = pulse width/time period.

Thanks for explaining.

x= 60 {total length of the wave as shown}.
time period = 60/3 = 20.

% of signal in 1 time period = (5/20) * 100 = 25.

Duty cycle = 25%.

Ton=5ms*3 = 15ms
T=60ms

Duty Cycle = Ton/T * 100%
DC = 15/60 * 100%
= 25%

WE KNOW ton = 5ms,
toff = ?
so 3*toff = 60ms-(3*ton)
3*toff = 60ms-(3*5ms)
3*toff = 60ms-15ms
toff = (45ms)/3
toff = 15ms

Therefor D = (ton)/T where T = ton+toff
= 5ms/(5ms+15ms)
= 0.25 @ 25%
