Answer 1

Answer

Price of pen and notebook=Rs.59

thus let price of pen be rs.x

thus price of notebook=59-x

thus

A.T.G.C.

2x+7[59-x]=115

2x+413-7x=115

413-5x=115

413-115=5x

198/5=x

39.6=x

thus price of notebook=59-x

                                       =59-39.6

                                        =Rs.19.4
