Question

If 10% is deducted from a bill rupees 7200 remains to be paid how much is the bill

Answer 1

Let the bill amount is = X

After 10℅ discount , the bill will be = X×10%

= X × 10/100

X/10

After 10% deduction the payable amount will be (X-X/10),

According this sum :---

X-X/10 = 7200

10X-X/10 = 7200

9X/10 = 7200

9X= 7200×10

X= 72000/9

X= 8000

Ans:--Original bill is 8000 ,

Answer 2

Original bill = 8000 rs.      

Step-by-step explanation:

According to the questions,

Lets assume that, original bill is 100%

10% deduction to the original bill,

it means, 90% = 7200 rs.

                1% =$\frac{7200}{90}$

then,        100% = $\frac{7200}{90}\times{100}$

                 100% = 8000rs.

Original bill = 8000 rs.
