Answers
Answer:
Energy consumed by 4 bulbs of 100 watt each.
Electric energy =
1000
PHD
=
1000
400×4×30
= 48 units
Energy consumed by 4 bulbs of 40 watt each
Electric energy =
1000
PHD
=
1000
160×6×30
= 28.8 units
Energy consumed by 2 fans of 60 watt each
Electric energy =
1000
PHD
=
1000
120×8×30
= 28.8 units
Total consumed electric energy = 48+28.8+28.8=105.6 unit
Energy consumed = Energy energy × rate per unit
= 105.6×5=528.00= Rs.528
