Question

A shopkeeper sold a material with 40% discount and the cost is 480 find the original cost of material?​

Answer 1

formula is 40/100 multiply 480

Answer 2

Given,

A shopkeeper sold a material with 40% discount and the cost is 480.

To Find,

The original cost of material? =?

Solution,

We can solve the question as follows:

It is given that a shopkeeper sold a material for a 40% discount. The cost of the material is Rs. 480. We have to find the original cost of the material.

Let the original cost of the material be = $x$

If he sold it for a 40% discount, then the final cost will be equal to the original cost subtracted by 40% of the original cost.

Therefore,

Final cost = $x - 40$% of $x$

It is given to us that final cost = $Rs.$ $480$

$480 = x - \frac{40}{100} x$ (We can write percentage in its decimal/fraction form by            

                         dividing it with 100)

$480 = \frac{100x - 40x}{100}$

$480 = \frac{60x}{100}$

$480 = \frac{3}{5}x$

$x = 480 * \frac{5}{3}$

$x = 800$

• Instead of doing the above calculations, we can also use the formula:

         $Final$ $cost$ = $Original$ $cost*$ $\frac{(100 - Discount)}{100}$

Hence, the original cost of the material is Rs. 800.
