Step-by-step explanation:
The given digits are 7,0,6 and repetition of digits is not allowed.
The one-digit numbers that can be formed are 7 and 6.
We are required to write 2−digit numbers.
Out of the given digits, the possible ways of choosing the two digits are
7,0;6,0;6,7
Using the digits 7 and 0, the numbers are 70.
Similarly, Using the digits 6 and 7, the numbers are 67 and 76.
Hence, all possible 2−digit numbers are
60,70,67,76
Now, we are required to write 3−digit numbers using the digits 7,0,6 and the repetition of the digits is not allowed. Keeping 0 at unit's place, 3−digit number obtained are 670 and 760.
Keeping 6 at unit's place, 3−digit number obtained are 706.
Keeping 7 at unit's place, 3−digit number obtained are 607.
Hence ,all possible 3−digit numbers are: 670,764,706 and 607.
All possible numbers using the digits 7,0 and 6 are
6,7,76,67,70,60,706,607,760,670
