Two bulbs each of 60 W and 80 W power are used for (1/4)th a day and (1/2) a day, respectively. Write the following steps in a sequential order to find the total number of units consumed by them when they are used for 30 days.
(a) Now, multiply E with 30, to get the energy consumed by them in 30 days.
(b) Find the electric energy consumed by each bulb in a day using `E_(1)=P_(1)t_(1)` and `E_(2)=P_(2)t_(2)`.
(c) Note down the powers of the bulbs and the time for which they are used per day as `P_(1), P_(2)` and `t_(1)`, `t_(2)` , respectively.
(d) Convert the time into hours.
(e) Find the total energy (E) consumed by them in one day, i.e., `E=E_(1)+E_(2)`.
(f) Write the energy in terms of units, i.e., commercial unit of electric energy.
