Detailed Solution

It is given a shop charges his customer 22% more than the cost price.
Let the cost price of DVD player be x.
Owner will take

= x + 22 % \times x

from the customer,
According to the question,

(x + \frac{22}{100} x) = 10980

\Rightarrow \frac{122}{100} x = 10980

\Rightarrow x = 10980 \times \frac{100}{122}

\Rightarrow x = 9000

, which is cost price of DVD player.
