Problem 5:
Find how many digits are there in the number which comes before 10, 100, 86, 42, 67?
Solution:
As given in the question,
The numbers are 10, 100, 86, 42, 67
We have to find the digits of the before numbers
For the number 10, the before number is 9
Therefore, it has one digit
For the number 100, the before number is 99
Therefore, it has two digits
For the number 86, the before number is 85
Therefore, it has two digits
For the number 42, the before number is 41
Therefore, it has two digits
For the number 67, the before number is 66
Therefore, it has two digits
Problem 6:

Problem 8:
Find how many digits are there in the number that is two numbers before 11, 67, 83, 44, 78, 101, 65?
Solution:
As given in the question,
The numbers are 11, 67, 83, 44, 78, 101, 65
We have to find the number of digits that are two numbers before it.
For the number 11, two values before the number is 8
Therefore, 8 is a single-digit number
For the number 67, two value before the number is 64
Therefore, 64 is a double-digit number
For the number 83, two value before the number is 80
Therefore, 80 is a double-digit number
For the number 44, two value before the number is 41
Therefore, 41 is a double-digit number
For the number 78, two value before the number is 75
Therefore, 75 is a double-digit number
For the number 101, two value before the number is 98
Therefore, 98 is a double-digit number
For the number 65, two value before the number is 62
Therefore, 62 is a double-digit number
