The product of the successor 999 and predecessor of 1001 is:
1 One lakh.
2 One billion.
3 One million.
4 One crore.
Explanation:
One million. Solution: Successor of 999 = 999 + 1 = 1000 Predecessor of 1001 = 1001 - 1 = 1000 Now, Product = (Successor of 999) × (Predecessor of 1001) = 1000 × 1000 = 1000000 = One million Hence, the correct option is (c).

If a is a whole number such that a + a = a, then a = ?
1 1
2 2
3 3
4 None of these.
Explanation:
None of these. Solution: Given: a is a whole number such that a + a = a If a = 1, then \(1+1=2\ne1\) If a = 2, then \(2+2=4\ne1\) If a = 3, then \(3+3=6\ne1\)

If a,b and c are whole numbers, then a + (b + c) = (a + b) + c. This property is called:
1 Associative property
2 Commutative property
3 Distribution property
4 None of the above
Explanation:
Associative property Solution: a + (b + c) = (a + b) + c is associative property of whole numbers.

Number of whole numbers between 38 and 68 is:
1 31
2 30
3 29
4 28
Explanation:
29 Solution: Option C is right Whole number starts from 0 and increase by 1 each They are 0, 1, 2, 3.... Whole numbers between 39 and 68 are 39, 40, 41... 66, 67 Hence 29 whole numbers between 38 and 68

Multiplicative identity is:
1 1
2 0
3 both
4 none
Explanation:
1 Solution: Definition of multiplicative identity. : an identity element (such as 1 in the group of rational numbers without 0) that in a given mathematical system leaves unchanged any element by which it is multiplied. If we multiply 1 with any number we will get the same number.
