An electric iron of 1100 W is operated for 2 hours daily. What will be the electrical consumption expenses for that in the month of April ? (The electric company charges Rs. 5 per unit of energy.)

Explanation

Data : `P=1100 W, t=2xx30=60 h`, Rs. 5 per unit of energy, expenses = ?
`N=(Pt)/(1000 W*h)//"unit")=(1100 W xx 60h)/(1000W*h//"unit")=66` units
Electrical consumption expenses
= 66 units `xx` Rs. 5 per unit
=Rs. 330
