Given
- Power = 1100 W
- Time/day = 2 hrs
- Cost = ₹5 per unit (kWh)
To Find
- Electric bill for the month of April (30 days)
Solution
☯ Total Cost = Power (kWh) × Time/day × Number of days × Cost per unit
- To calculate the cost we have to convert the unit of power from watt to kWh
━━━━━━━━━━━━━━━━━━━━━━━━━
✭ According to the Question :
➞ Total cost = Power × Time/day × Number of days × Cost per unit
- Power = 1100 W = 1100/1000 = 1.1 kWh
- Time/day = 2 hrs
- Number of days = 30
- Cost per unit = ₹5
➞ Total cost = 1.1 × 2 × 30 × 5
➞ Total cost = 66 × 5
➞ Total cost = ₹330
∴ The electric bill for the month of April is ₹330
