Ostrovityanka [42]

Answer:

See explanation below.

Step-by-step explanation:

Let's say, $x$ represents the sale price of radio.

Then the marked price of the radio is $1.25x$

The cost price of the radio is $(1.25x)(0.70)$

The discount is simply 25% because the radio is being sold at 25% less then the marked price.

The gain percent is given as:

$\frac{x-1.25x\times \:0.70}{x}\times 100\\\\=12.5\%$

The radio is being sold at 12.5% gain.

Best Regards!
