Example 26: Avan  ka buys 3 L 245 mL of orange juice and 4 L 320 mL of apple juice, and
                                  prepares fruit punch by mixing the juices. She pours 1 L 450 mL of fruit punch
                                  into the glasses. How much fruit punch is s  ll le  ?
                    Solu  on:     Amount of orange juice bought by Avan  ka
                                                                                                       Calcula  on
                                               = 3 L 245 mL                                           L         mL

                                  Amount of apple juice bought by Avan  ka                            3      2   4   5
                                               = 4 L 320 mL                                      +    4      3 2 0

                                    Amount of fruit punch prepared on mixing                         7      5   6   5
                                     both the juices = 3 L 245 mL + 4 L 320 mL
                                                                                                      L         mL
                                                       = 7 L 565 mL
                                                                                                      7      5   6   5
                                  Thus, the amount of fruit punch le   a  er she
                                                                                                 –    1      4 5 0
                                  poured 1 L 450 mL of it into the glasses
                                                                                                      6      1   1   5
                                               = 7 L 565 mL – 1 L 450 mL = 6 L 115 mL

                                  So, 6 L 115 mL of fruit punch is s  ll le  .
