Answer:

  • The trader was supposed to cell the TV for sh. 27000 in order to make 20% profit

==============

Let the cost price is x.

We have:

  • x - 20% = 18000

Solve it for x:

  • x - 0.2x = 18000
  • 0.8x = 18000
  • x = 18000/0.8
  • x = 22500

The cost is 22500, find selling price with 20% profit:

  • 22500 + 20% =
  • 22500 + 0.2*22500 =
  • 22500*1.2 =
  • 27000
