Question 85

If 21% of an electricity bill is discounted, Rs 1817 is still to be paid. How much was the original bill amount?

Solution

Let the original bill amount = $$Rs. 100x$$

If 21% of an electricity bill is deducted, bill left = $$\frac{100 - 21}{100} \times 100x = 79x$$

According to ques, => $$79x = 1817$$

=> $$x = \frac{1817}{79} = 23$$

$$\therefore$$ Original bill amount = $$100 \times 23 = Rs. 2300$$

=> Ans - (C)
