Question

F) The marked price of a radio is 25 % above the selling price and the cost pr

30 % less than its marked price. Find the discount percent and gain percent.
​

Answer 1

See explanation below.

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:

`(x-1.25x* \:0.70)/(x)* 100\\\\=12.5\%`

The radio is being sold at 12.5% gain.

Best Regards!
