Question

If 10 percentage is decreased from the bill 279 remain to be paid how much is the original bill

Answer 1

Answer:

Original bill = Rs.310

Step-by-step explanation:

Let the original bill in Rupees = x

If 10% is decreased from the bill the bill becomes 0.9x

This amount is given to be 279

=> 0.9x = 279

=> x = 279/0.9

=> x = 310

The original bill is of Rs.310

Answer 2

Given: 10% is decreased from the bill then 279 remain.

To find: We have to find the original bill.

Solution:

To determine the value of the original bill we have to follow the below steps-

Let the original bill be of x rupees.

If 10% is decreased from the original bill that is from x rupees then the bill becomes-

$x - \frac{10x}{100} \\ x - \frac{x}{10} \\ \frac{9x}{10}$

The reduced bill is 9x/10 rupees.

This bill amount after the discount is 279 rupees.

So, we can write-

$\frac{9x}{10} = 279 \\ 9x = 279 \times 10 \\ x = 310$

The value of x is 310 rupees.

The original bill of 310 rupees.
