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:
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
