we know that
P= work/time
work = power * time
and then calculate the work frst for the 100 watt and then for the 4 sixty watt bulbs and then add the both work ths will be the energy consume in 1 day so u will hav to multiply your ans by 30 to get the energy consumed in 30 days....hope it would hav cleared ur doubt
