Given the current price of a TV = $600

The current price is the price after 20% cut:

Then let us assume that x is the original price of the TV before reduction.

Then :

Current price = original price - reduction amount

==> 600 = x - (20% * x)

==> 600 = x - ( 20/100) x

==> 600 = x - ( 0.2) x

==> 600 = 0.8 x

Now divide by 0,8

==> x = 600/ 0.8 = 750

**Then the original price of the TV before the reduction = $ 750**
