Answer 1

To find:

The numbers with the digit 7 either in 'Ones' place or in 'Tens' place

Step-by-step explanation:

• Let us take 7 in 'Ones' place first. Then we will have numbers: 7, 17, 27, 37, 47, 57, 67, 77, 87, 97, and so on.

• Now we take 7 in 'Tens' place. Then we will have numbers: 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 170, 171, and so on.

• We can also take large numbers with 7 in either 'Ones' place or 'Tens' place. In that we will have infinite number of numbers having 7 with those conditions.

Answer:

7, 17, 27, 37, 47, 57, 67, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 87, 97, 170, 171, ... ... .
