        We write 1 in ones place.                          We write 8 in ones place.

        Example 2: Make the largest and smallest three digit number by

                           using digits 2, 6 and 4. You may repeat the digits.
        Solution:


        Let  us  first  write  the  largest  Now  let  us  write  the  smallest

        number.                                              number.





        We will first find the digit in the  We will first find the digit in the
        hundreds place.                                      hundreds place.
        We know that 6 is greater than 4  We know that 2 is smaller than 4
        and 2 both, so digit in hundreds  and 6 both, so digit in hundreds

        place is 6.                                          place is 2.

                           H    T    O                                         H    T    O

                           6                                                   2


        We  still  have  6, 4  and  2  as  we                We  still  have  6, 4  and  2  as  we
        are allowed to repeat.                               are allowed to repeat.

        We know that 6 is greater than 4                     We know that 2 is smaller than
        and 2 both, so digit in tens place                   4  and  6  both,  so  digit in  tens

        is also 6.                                           place is also 2.

                           H    T    O                                         H    T    O

        In the same way digit at ones
                                                             In  the  same  way  digit  at  ones
        place is also 6.
                                                             place is also 2.
