Answer 2

Answer:

The cost price of the fan​ is Rs. 400 .

Step-by-step explanation:

Given -

Selling price - Rs. $448$

Profit = 12%

To find -

The cost price of the fan​

Solution -

As we know that,

$Profit \:\: percentage= \frac{S.P.-C.P.}{C.P.} \times100$

Where,

S.P. - Selling price

C.P. - Cost price

Let, the cost price is x

Put the given value in given the formula we get

$12$ = $\frac{448-x}{x} \times100$

$12x =(448-x)\times 100$

$12x= 44800-100x$

$100x+12x= 44800$

$112 x= 44800$

Divide both side by 112 we get

$x=400$

∴  The cost price of the fan​ is Rs. 400 .
