Answer 1

Answer

• Total consumption is 11.4 kWh
• The cost will be ₹28.5

Explanation

Given

• There are 4 bulbs
• Power = 100 W
• 5 Fans each of 110 W
• Time = 12 hours daily

To Find

• Electrical energy consumed a d the total cost per day

Solution

• → E = P×t
• P = 100 W = 0.1 kW
• t = 12
• → E = 0.1 × 12
• → E = 1.2 kWh

For 4 lights

• → 1.2 × 4
• → E = 4.8 kWh

Similarly,

• → E = P×t
• P = 110W = 0.11
• t = 12
• → E = 0.11×12
• → E = 1.32 kWh

For 5 fans

• → 1.32×5
• → E = 6.6 kWh

Total Consumption

• → 4.8+6.6
• → 11.4 kWh

Cost

• → 11.4×2.50
• → ₹28.5
