Question

pawan marked the price of a speaker set 22% above its cost price​

Answer 1

Answer:

1900 Rs.

Step-by-step explanation:

Let the cost price of the speaker set = x Rs.

Marked price of the set = $x+\frac{22}{100} x$

                                        = $\frac{122}{100}x$

Selling price of the set = Marked price - 17% of marked price

                                      = Marked price (1 - 17/100)

                                      = $\frac{122}{100}x(1-\frac{17}{100})$

                                      = $\frac{122x}{100}$ × $\frac{83}{100}$

                                      = 1.22x × 0.83

                                      = 1.0126x

Profit earned = Selling price - Cost price

1.0126x - x = 23.94

or, x(1.0126 - 1) = 23.94

or, 0.0126x = 23.94

or, x = 23.94/0.0126

       = 1900

Thus, the cost price of the speaker set = 1900 Rs.
