(B) Step $1$: Calculate the total power consumption.Total power = (Number of tubes) $	imes$ (Power per tube) = $5 	imes 40 \, W = 200 \, W$.Step $2$: Convert power to kilowatts $(kW)$.$200 \, W = 200 / 1000 \, kW = 0.2 \, kW$.Step $3$: Calculate the total energy consumed in kilowatt-hours ($kWh$ or units).Energy = Power $(kW)$ $	imes$ Time $(h)$ = $0.2 \, kW 	imes 20 \, h = 4 \, kWh$ (or $4$ units).Step $4$: Calculate the total cost.Total cost = (Total units) $	imes$ (Cost per unit) = $4 	imes ₹ 0.50 = ₹ 2.00$.

$A$ house is fitted with $5$ tubes each of $40 \, W$. If all the tubes are lighted for $20$ hours and if the cost of electrical unit is ₹ $0.50$,the total cost of electricity consumed is (in ₹)
