Calculate \(25\%\) of \(1000\):
\(25\%\) of \(1000 = \frac{25}{100} \times 1000 = 250\)
Calculate \(1\%\) of the result from step 1:
\(1\%\) of \(250 = \frac{1}{100} \times 250 = 2.5\)
Calculate \(1\%\) of the result from step 2:
\(1\%\) of \(2.5 = \frac{1}{100} \times 2.5 = 0.025\)
An electricity utility company charges ₹7 per kWh. If a 40-watt desk light is left on for 10 hours each night for 180 days, what would be the cost of energy consumption? If the desk light is on for 2 more hours each night for the 180 days, what would be the percentage-increase in the cost of energy consumption?
