Q8: Every whole number has a successor.
Ans:
True

Every whole number has a successor because you can always add 1 to any whole number to get the next number.

Q9: There is no largest whole number.
Ans: 
True

Whole numbers go on infinitely, so there is no largest whole number.

Q10: The sum of two even numbers is always an odd number.
Ans:
False

Q11:  0 is neither positive nor negative.
Ans:
True

0 is a neutral number; it is neither positive nor negative.

Q12: The predecessor of 1 is 0.
Ans: 
True

The predecessor is the number that comes before a given number. For 1, the predecessor is 0.

Answer the following questions 

Q13: Determine the sum of the four numbers as given below:
i. Successor of 32
ii. Predecessor of 49
iii. The predecessor of the predecessor of 56
iv. The successor of the successor of 67
Ans:

Successor of 32:
Successor means the next number, so the successor of 32 is 33.

Predecessor of 49:
Predecessor means the number before, so the predecessor of 49 is 48.

The predecessor of the predecessor of 56:
First, find the predecessor of 56, which is 55. Then, find the predecessor of 55, which is 54.

The successor of the successor of 67:
First, find the successor of 67, which is 68. Then, find the successor of 68, which is 69.

Sum:
Now, add these four numbers together:
33 + 48 + 54 + 69 = 204
Final Answer: 204

Q14: Write the predecessor of:
a. 94
b. 10000
c. 208090

Ans:
a. Predecessor of 94:
The predecessor of 94 is 93.

b. Predecessor of 10000:
The predecessor of 10000 is 9999.

c. Predecessor of 208090:
The predecessor of 208090 is 208089.

Q15: How many whole numbers are there between 381 and 401?
Ans: 
To find the number of whole numbers between 381 and 401, subtract the smaller number from the larger number and then subtract 1 from the result (because we exclude the endpoints).

401 - 381 = 20

Since we include both 381 and 401, there are 19 whole numbers between them.

Final Answer: 19

Q16: A mobile number consists of ten digits. The first four digits of the number are 9, 9, 8, and 7. The last three digits are 3, 5, and 5. The remaining digits are distinct and make the mobile number, the greatest possible number. What are these digits?
Ans: 
To make the greatest possible number, choose the largest available digits for the remaining three positions. The digits left to use are 0, 1, 2, 4, and 6. We should select the largest three of these digits.

The largest three available digits are: 6, 4, and 2.

So, the greatest possible mobile number with the given digits would be:

9987642355

Final Answer: 6, 4, and 2
