. A trader bought A TV set for Birr 2000 and sold it at loss of 11/2% what:was the selling price?​
olga nikolaevna [1]

Answer:

1890

Step-by-step explanation:

Loss = 11/2 % = 5.5 %

Cost price = 2000

Loss = 5.5% of cost price

         = 5.5% * 2000

         = \frac{5.5}{100}*2000\\\\= 5.5*20\\= 110

Selling price = Cost price - loss

                      = 2000 - 110

                      = 1890
