Answer 1

if the selling price is 80(100-20),then the cost price is 100
............................... 1 ................................................. 100/80
............................... 13500 ......................................... 13500*100/80
                                                                                      =16875

Answer 2

SP of the Machine = 13500 Rs

He made 20 % loss.

That means he sold the machine at (100-20)% = 80 % of CP

Hence CP = 13500*100/80= 16875

She bought the machine at  Rs 16875
