Energy Consumed= 4 × P. × T. 
= 4 × 0.04kw × 5h . nergy used by tube lights in one day=60*5*4=1.2kwh. Energy Consumed= P. × T. 
= 0.1kw × 6h 
= 0.6 Units. 
A Washing machine of 400W for 3 hrs. 
So, Energy Consumed= P. × T. 
= 0.4kw× 5h 
= 1.2 Units.  otal Energy used in one day=0.8+0.6+1.2+1.2=3.8kwh
Total Energy used in 30 days =30*3.8=114 k w h. the bill for the entire month = 114*1.8= Rs. 205.2
