Explanation:
Given:-
Power= 60 Watt
Everyday Use = 10 Hours
Total Days= 30
Cost Of elctricity per unit= 3.50 Rs.
Find:-
Total amount to be paid in 30 days
Given:-
The days can be calculated in total hours used in 30 days
Hence, Days x Everyday Use = 30 x 10 = 300 Hours
Convert, 60 Watt into Kwatt = 60/1000
By Formula,
Unit= Kwatt x Time (in hours)
U= 60/1000 x 300
U= 18
Hence, total unit used is 18.
By Formula,
Cost= Unit x Rupees per unit
Cost= 18 x 3.50
Cost= 63 Rupees
Therefore, the amount to pay in 30 days is 63 Rupees.
