Question
If 20% of an electricity bill is deducted, then Rs. 100

Let the original bill be Rs. x. After deduction of 20%, the remaining amount is Rupees 100. => x - 20% of x = 100 => x - (20/100)x = 100 => x - x/5 = 100 => 5x - x = 500 => 4x = 500 => x = 500/4 = 125 Therefore, the original bill is Rs. 125.
