Answer 1

Answer:

The cost price was 500.

Step-by-step explanation:

Let x be the original price.

$x\times(1+12\%)=560$

$x\times(1+0.12)=560$

$1.12x=560$

$1.12x/1.12=560/1.12$

$x=500$

Answer 2

Answer:

500

Solution,

$profit \: percent = 12 \\ selling \: price = 560 \\ cost \: price \\ = \frac{sp \times 100}{100 + profit \: percnt} \\ = \frac{560 \times 100}{100 + 12} \\ = \frac{56000}{112} \\ = 500$

hope this helps...

Good luck on your assignment...
