Answer 1

Step-by-step explanation:

let the CP be x

SP = 640

profit% = 28%

then, profit% = profit/CP* 100

28% = profit * 100

----------

x

28 * x / 100= profit

28x /100 = profit

and, CP + profit = SP

x + 28x= 640

-------

100

100x + 28x= 640

-----------------------

100

128x = 640 * 100 (by cross multiplication)

128x = 64000

x = 64000

-----------

128

x = 500

CP = 500 (answer)

Answer 2

Answer:

Given:

By selling a bed sheet for rupees 640 A shopkeeper earns a profit of 28%

Find:

how much did it cost the shopkeeper.

Calculation:

$\sf\rightarrow \frac{128}{100} \times x = 640$

Let x be the cost price of bed sheet.

$\sf\rightarrow x = 640 \times \frac{100}{128}$

$\sf\rightarrow x = 500$

Therefore, 500 is the cost of shopkeeper.
