Question

An electric meter reads 8950 KWh at the end of the month, while at the beginning of the month the reading was 8833 KWh. How many units of electricity .are consumed ? If one unit costs Rs. 4.30, find the cost of the electrical energy consumed.

Answer 1

Final reading of the meter $=8950KWh$

Initial reading of the meter $=8833KWh$

$\therefore$Energy consumed during the month$=8950-8833=117KWh$

Rate of 1 unit $=Rs.4.30$

$\therefore$ Cost of 117 units$=Rs.4.30\ast 117$

$=Rs.503.10$
