Answer 2

Answer:

21 paisa

Step-by-step explanation:

amount of mney she spend = 42 %

amount of money left = (100-42)%

                                    = 58 %

total money she had = (29 x 100/58) paisa

                                   = 50 paisa

therefore, cost of the book = (total money -money left with her )

                                             = (50 - 29) paisa

                                              = 21 paisa
