Given :
- 3 bulb of 40 W for 6 hours per day
- 4 tubelights of 50 W for 8 hours per day
- 4 T.V of 120 W for 6 hours per day
- Rate of electricity per unit is 2.50
To find :
- Electricity bill of June
According to the question,
➨ Energy consumed by the bulb = 40/1000 × 6
➨ Energy consumed by the bulb = 0.24
Now,
➨ Energy consumed by 3 bulb = 0.24 × 3 = 0.72 KWh
➨ Energy consumed by tubelight = 50/1000 × 8
➨ Energy consumed by tubelight = 0.4 KWh
Now,
➨ Energy consumed by 4 tubelight = 0.4 × 4 = 1.6 KWh
➨ Energy consumed by T.V = 120/1000 × 6
➨ Energy consumed by T.V = 0.72 KWh
Now,
➨ Energy consumed by 4 T.V = 0.72 × 4
➨ Energy consumed by 4 T.V = 2.88 KWh
So,
➨ Total energy consumed in 1 day = 0.72 + 1.6 + 2.88
➨ Total energy consumed in 1 day = 5.2 KWh
➨ Energy consumed in June = 5.2 × 30
➨ Energy consumed in June = 156 KWh
Note : As we know that June is of 30 days
➨ Total cost = 156 × 2.50
➨ Total cost = Rs. 390.
