MCQ Questions for Class 6 Maths Whole Numbers Quiz 5

State true or false of the following.
The whole number

$1$ has

$0$ as predecessor.

0%
True
0%
False

Explanation

The set of whole number system starts from the number

$0$ .

And the set is

$\{0,1,2,3,.....\}$ .

So it is clear that the number

$1$ has

$0$ as predecessor in the whole number system.

State true or false of the following.

$0$ is less than every natural number.

0%
True
0%
False

Explanation

The set of natural numbers is

$\{1,2,3,......\}$ .

It is clear that each natural number is greater than

$0$ .

State true or false of the following.
Every whole number has its predecessor.

0%
True
0%
False

Explanation

The statement is false.

As, consider

$0$ , which is a whole number but it has no predecessor.

Mark the correct alternative of the following.
How many three digit numbers are there in all?

0%
$100$
0%
$900$
0%
$99$
0%
$102$

Mark the correct alternative of the following.
The product of the successor and predecessor of

$99$ is?

0%
$9800$
0%
$9900$
0%
$1099$
0%
$9700$

Explanation

The successor and the predecessor of the number

$99$ are

$99+1=100$ and

$99-1=98$ respectively.

So the product of the successor and the predecessor is

$98\times 100=9800$ .

Mark the correct alternative of the following.
The predecessor of

$1$ million is?

0%
$9999$
0%
$99999$
0%
$999999$
0%
$1000001$

Explanation

The predecessor of the number

$1$ million is the number just before it and it is

$10,00000-1=999,999$ .

Mark the correct alternative of the following.
The predecessor of

$1$ in whole numbers is?

0%
$0$
0%
$-1$
0%
$2$
0%
None of these

Explanation

The set of whole number system starts from

$0$ , so the predecessor of the number

$1$ is

$0$ in whole number system.

Mark the correct alternative of the following.
The successor of 1 million is?

0%
$10001$
0%
$100001$
0%
$1000001$
0%
$10000001$

Explanation

We know that, a successor is a number that appears immediately after a given number.

We obtain the successor of a number by adding

$1$ to that number.

The given number is

$1\ million$

$\Rightarrow 1000000$

$\therefore \$ The its successor

$=1000000+1=1000001$ .

Hence, the successor of

$1\ million$ is

$1000001$ .

Every whole number has its predecessor.

0%
True
0%
False

Explanation

$\textbf{Reason:}$ The predecessor of a number is one less than the given number.

Predecessor of

$0$ (which is a whole number) does not exist.

So, we can say that every whole number except

$0$ has its predecessor.

$\therefore\ \textbf{The given statement is False}.$

If the sum of two distinct whole numbers is odd, then their difference also must be odd.

0%
True
0%
False

Explanation

Let us assume two whole numbers

$5$ and

$6$ then:

Their sum is

$5 + 6 = 11$ (

$11$ is odd)

And their difference is

$6 - 5 = 1$ (

$1$ is odd)

Clearly, the sum and difference are both odd.

$\textbf{Therefore the given statement is True}.$

Number of whole numbers lying between

$-5$ and

$5$ is

0%
$10$
0%
$3$
0%
$4$
0%
$5$

Explanation

Whole number consists of all positive integers including

$0$ .

We know that, integers lying between

$-5$ to

$5$ are

$-4, -3, -2, -1, 0, 1, 2, 3$ and

$4$ .

As per the question, we have to consider the whole number from the list of numbers.

$\textbf{So, whole numbers lying between -5 and 5 are 0, 1, 2, 3 and 4}$ .

$\therefore$

$\textbf{Option (d) is correct}$ .

All whole numbers are integers.

0%
True
0%
False

Explanation

Whole numbers are natural numbers including zero.

Whole numbers are

$\bf{0, 1, 2}$ …....

Integers are combinations of positive numbers, negative numbers and zero .

Integers are …….

$-3, -2, -1, \bf{0, 1, 2, 3}$ …….

So, we can say that all whole numbers are integers.

$\therefore$

$\textbf{The given statement is True}$

Natural numbers are closed under addition.

0%
True
0%
False

Explanation

$\textbf{Reason:}$ Closure property of addition of natural numbers states that the addition of two or more natural numbers

always results in a natural number.

Clearly any two or more natural numbers added results in a natural number.

For example:

$3 + 2 = 5$ a natural number

$43 + 67 + 2 = 112$ a natural number

$\therefore\ \textbf{The given statement is True}.$

There is a whole number which when added to a whole number, gives the number itself.

0%
True
0%
False

Explanation

Zero is the whole number which when added to any whole number gives the same whole number as a result.

For example:

$3 + 0 = 3$

$4009 + 0 = 4009$

$\therefore\ \textbf{The given statement is True}.$

Natural numbers are not closed under multiplication.

0%
True
0%
False

Explanation

$\textbf{Reason:}$ Closure property of multiplication of natural numbers states that the multiplication of two or more natural

numbers always results in a natural number.

Clearly two or more natural numbers multiplied results in a natural number.

For example:

$3 \times 2 = 6$ a natural number

$20 \times 100 = 2000$ a natural number

$\therefore\ \textbf{The given statement is False}.$

Between any two natural numbers, there is one natural number.

0%
True
0%
False

Explanation

There is no natural number between

$5$ and

$6$ .

$\therefore\ \textbf{The given statement is False}.$

Natural numbers are closed under subtraction.

0%
True
0%
False

Explanation

$\textbf{Reason:}$ Closure property for natural numbers is followed when two natural numbers undergo any arithmetic

operation then the result obtained is always a natural number.

The subtraction of some natural numbers may not give a natural number.

For example:

$5 - 7$ is not a natural number,

$20 - 435$ is not a natural number

$\therefore\ \textbf{The given statement is False}.$

The addition is commutative for natural numbers.

0%
True
0%
False

Explanation

The addition of any two natural numbers does not depend on the order in which they are taken

(also known as commutativity),

For example:

$3 + 2 = 2 + 3 = 5$

$20 + 100 = 100 + 20 = 120$

$\therefore\ \textbf{The given statement is True}.$

Find value of K

$19 \times 12+19= 19\times (12+K)$

0%
$1$
0%
$2$
0%
$3$
0%
$-1$

Explanation

Let, the member is

$K$

$19 \times 12+19= 19\times (12+K)$

$228+19=19 \times 12+19 \times K$

$228+19=228 +19 \times K$

$19 \times K=228+19-228$

$19 \times K=19$

$K=\dfrac{\not{19}}{ \not{19}}=1$

Number of whole numbers between

$38$ and

$68$ is

0%
$31$
0%
$30$
0%
$29$
0%
$28$

Explanation

The number of whole numbers between any two whole numbers is:
The difference of the numbers

$-1$
So, number of whole numbers between

$38$ and

$68 = 68 - 38 - 1$

$= 29$

$\therefore\ \textbf{Option C is correct}$

$4+6 = ?$

By observing the given figure, what will occur in the place of question mark

$(?)$

0%
$8$
0%
$9$
0%
$10$
0%
$11$

Which of the following is not true?

0%
$(7+8)+9=7+(8+9)$
0%
$(7\times 8)\times 9=7\times (8\times 9)$
0%
$7+8\times 9=(7+8)\times (7+9)$
0%
$7\times (8+9)=(7\times 8)+(7\times 9)$

Explanation

$\textbf{Step 1: Recall Associative property of addition and multiplication.}$

By Associative property of addition and multiplication we have

$(7 + 8) + 9 = 7 + (8 + 9)$ and

$(7 \times 8) \times 9 = 7 \times (8 \times 9)$ are correct

$\therefore\ \textbf{Option A and B are true}$ .

$\textbf{Step 2: Recall Distributive property of multiplication over addition}$

By distributive property of multiplication over addition we have

$7 \times (8 + 9) = (7 \times 8) + (7 \times 9)$ is correct.

$\textbf{So Option D is also true}$ .

$7 + 8 \times 9 = 7 + 72$

$= 79$

$(7 + 8) \times (7 + 9) = 15 \times 17$

$= 255$

$7 + 8 \times 9 = (7 + 8) \times (7 + 9)$ is incorrect.

$\therefore\ \textbf{Option C is not true}$ .

$\textbf{Therefore the correct option is C}$ .

Study the following pattern and hence write the next step.

$9 \times 3 = (10-1) \times 3$

$99 \times 3 = (100-1) \times 3$

$999 \times 3 = (1000-1) \times 3$

0%
$9999 \times 3 = (1000-1) \times 3$
0%
$9999 \times 3 = (10000-1) \times 3$
0%
$999 \times 3 = (10000-1) \times 3$
0%
None of these
