We get 2, 0, 3 and 6

                            The required number is  2036.


        Example 17:  Write the largest  and  the  smallest number of  4 digits

                            using the digits 2, 1, 3 and 4. Repetition of digits is
                            allowed.

        Solution:           We have the digits 2, 1, 3 and 4.

                            First we will write the largest number.


                            The largest of the given digits is ‘4’ so the largest number
                            is 4444.

                            Now let us write the smallest number.


                            The smallest digit is 1, so the smallest number is 1111.


        Example 18:  Write  the  smallest  number  using  the  digits  4,  7,  0,  2.
                            Repetition of digits is allowed.


        Solution:           We have the digits 4, 7, 0  and 2. The smallest digit is 0.
                            But we cannot write 0 at thousands place. So we write 2
                            at thousands place and the required number is 2000.



                                                 EXERCISE 1.8



         A.  Make the largest and the smallest numbers using each digit only once.


                   Digits                    Largest Number               Smallest Number

              1.  4, 2, 0, 8

              2.  1, 8, 7, 3


         B.  Make the largest and the smallest numbers of 4 digits using the given
              digits. You may repeat the digits.

                   Digits                    Largest Number               Smallest Number


              1.  3, 0, 2, 9

              2.  0, 2, 1, 8


                                                                                                              103
