                example 3. A bucket contains 10 L 234 mL of water. A mug has 1 L 197 mL of water.

                How much water is there in both the containers?
                Solution.                                                       L     mL

                                                                                       1  1
                             Water in bucket                           =       1 0    2 3 4

                             Total water in mug and bucket             =        1 1    4 3 1

                example 4.  The Sharma family consumed 8 L 350 mL of milk and the Verma family
                               consumed 11  L 125 mL of milk in a week. Who consumed more and by

                               how much?
                Solution.                                                       L      mL

                                                                                 10  10 12

                             Milk consumed by Vermas                   =       1 1    1 2 5
                             Milk consumed by Sharmas                  = –        8   3 5 0
                             Difference in consumption                 =              2  7 7 5

                The Verma family consumed 2 L 775 mL more milk than the Sharma family.

                            Exercise 9H

                    1.  Find the sum.

                .       a.       L    mL               b.        L   mL                c.       L    mL
                                 35 245                         180 265                        395 034
                              + 63 107                        +     59 470                   +     65 028

                    2.  Write in the vertical form and add the following:

                        a.  50 L 725 mL and 10 L 225 mL                     b.  32 L 864 mL and 18 L 435 mL

                        c.  72 L 70 mL and 25 L 750 mL                      d.  7 L 65 mL and 18 L 456 mL
