                  Example 2: There were 5009 bags of rice in a godown. If 3639 bags are taken out, how
                  many bags will remain in the godown?

                  Solution:                                                                th H     t    O
                                                                                           4    9   10
                                 Number of bags in the godown                       =      5    0   0    9
                                 Number of bags taken out                           = – 3       6   3    9
                                 Number of remaining bags                           =      1    3   7    0

                                  Thus, 1370 rice bags has left in the godown.
                  Example 3: The sum of two numbers is 8197. If one of the numbers is 3994, find the

                  other number.
                  Solution:                                                                th H     t    O

                                                                                           7   11
                                 The sum of two numbers                             =      8    1   9    7

                                 One number                                         = – 3       9   9    4
                                 Other number                                       =      4    2   0    3

                                  Thus, the other number is 4203.
