35%. Find the cost price of the pen, which Is marked at Rs 30.

Answer 1

Answer:

Rs.20

Step-by-step explanation:

Selling price of the pen = $\frac{90}{100}$ x 30

                                       =Rs.27

Cost = $\frac{135}{100}$ x $x$ = 27

                    $x$ =27 x $\frac{100}{135}$

                       =20

So, cost is Rs.20
