                  addition and subtraCtion oF Money

                  To add or subtract the money, follow these steps:
                  Step 1: Arrange the given amounts in columns such that the dots                            Note

                  remain in one column.                                                                Regroup paise into
                  Step 2: Add or subtract the amounts as ordinary numbers.                             rupees if required.

                  Step 3: Put a dot in the sum in the dots column.

                  example 1: Add `70.20 and `25.45.                       example 2: Add `102.75 and `225.25.

                  Solution:        ` 7 0 . 2 0                            Solution:                    1     1

                                + ` 2 5 . 4 5                                               ` 1 0 2 . 7 5
                                   ` 9 5 . 6 5                                           + ` 2 2 5 . 2 5
                                                                                            ` 3 2 8 . 0 0

                         Thus, `70.20 + `25.45 = `95.65              Thus, `102.75 + `225.25 = `328.00

                  example 3:  Subtract `423.25 from `533.50. example 4:  Subtract `109.25 from

                                                                                        `423.75.
                  Solution:                         4 10                  Solution:                 1 13

                                   ` 5 3 3 . 5 0                                            ` 4 2 3 . 7 5
                                – ` 4 2 3 . 2 5                                          – ` 1 0 9 . 2 5
                                   ` 1 1 0 . 2 5                                            ` 3 1 4 . 5 0

                       Thus, `533.50 – `423.25 = `110.25.      Thus, `423.75 – `109.25 = `314.50.

                  example 5: Ram bought a toy for `210.50 and a pair of shoes for `579.75. How much
                  money did he spend in total?

                  Solution:                                                  1   1

                               The cost of the toy        =           ` 2 1 0 . 5 0

                               The cost of a pair of shoes   = + ` 5 7 9 . 7 5
                               The total cost of both items =         ` 7 9 0 . 2 5                      `  210.50  `  579.75

                                 Thus, Ram spent `790.25 in total.

                  example 6: Sanya wants to buy a mobile that costs `7650.50. She has only `6475 in her
                  purse. How much more money does she need to buy the mobile phone?

                  Solution:    Sanya subtracted a smaller amount from the bigger amount to check how
                                 much more money does she need to buy the mobile phone.
