            Addition of Money


            Addition without regrouping

            Example          :  Kanika bought a notebook for ` 80.20 and a pen for ` 15.25.

                                 How much money did she spend in all ?

            Solution         :           ` 8 0 . 2 0
                                                                         Add paise to
                                   +   ` 1 5 . 2 5                    paise and  rupees


                                         ` 9 5 . 4 5                       to rupees.


                                   Thus, Kanika spent ` 66.75 in all.

            Addition with regrouping


            Example          :     Add ` 10.85 and ` 45.40


            Solution         :     ` 10.85 + ` 45.40  = ?
                                            1

                                        ` 1 0 . 8 5

                                   +   ` 4 5 . 4 0              Þ  85 P  + 40 P   =  125 P

                                        ` 5 6 . 2 5                  125 P = 100 P + 25 P

                                                                     = 1 rupee 25 paise = ` 1.25

                                Thus, ` 10.85 + ` 45.40 = ` 56.25
