Question

3.
A piano is sold for * 42,500 at a loss of 15%. For how much should it have been sold to earn a profit of 15% ?
​

Answer 1

Answer:

when piano is sold at a loss the equation is

$x -15\%x = 42500$

$85x \div 100 = 42500$

$x = 50000$

So the original price of the piano is 50000.

If it would have been sold at profit the cost would have been

$x + 15\%x$

$5 0000 + (85 \times 50000) \div 100$

$= 50000 + 7500$

$= 57500$

So it should have been sold at 57500 to earn a profit

Answer 2

Step-by-step explanation:

when piano is sold at a loss the equation is

=

42500

x−15%x=42500

85

�

÷

100

=

42500

85x÷100=42500

=

50000

x=50000

So the original price of the piano is 50000.

If it would have been sold at profit the cost would have been
