100W bulb remains in the circuit, will illumination increase
or decrease?

Answer / ammad
Decrease.... Because the illumination is now being done
only by 100w bulb. If 60W bulb would have been connected
then the net power would have been 160W. Since now, the
power output is reduced to 100W this means that the
illumination would decrease....
