Question

Form the greatest and the smallest $3$ digit numbers using any three different digits with the condition that digit $6$ is always at the unit place.

Answer 1

Find the greatest and the smallest numbers:

The digits available for the formation of numbers are $0,1,2,3,4,5,6,7,8$ and $9$.

As it is given in the question that digit $6$ is always at the unit place.

So, one of the three required digits is $6$.

Now, using the different available digits and $6$, the numbers formed are as follows,

The greatest number $=986$

And, the smallest number $=106$

Hence, the required greatest and smallest three-digit numbers are $986$ and $106$ respectively.
