Question 1
1 / -0

Which of the following option is not true with respect to given number line?

A
$$B$$ is greater than $$-10$$

B
$$A$$ is greater than $$0$$

C
$$A$$ is greater than $$B$$

D
$$B$$ is greater than $$0$$

Solution

We have,
$$A=8$$ and $$B=-4$$
The numbers on the number line increase on moving from left to right on the number line. The point $$B$$ is left to the number $$0$$, so $$B$$ is less than $$0.$$.
$$A. \,-4 > -10 \Rightarrow B > -10$$ True
$$B$$ is right to $$-10$$. So, $$B$$ is greater.

$$B.\, 8>0 \Rightarrow A > 0$$ True
$$A$$ is right to $$0$$. So, $$A$$ is greater.

$$C. A > -4 \Rightarrow A > B$$ True
$$A$$ is right to $$B$$. So, $$A$$ is greater.

$$D. \, As \,-4<0 \Rightarrow B < 0$$. So, $$B> 0$$ is false.
$$0$$ is right to $$B$$. So, $$0$$ is greater.
Question 2
1 / -0

Which situation is best represented by the integer $$-12$$?

A
The length of curtains is increased by $$12$$ inches

B
The price of petrol is reduced by Rs. $$12$$

C
The size of picture is enlarged by $$12$$ percent

D
The temperature rises by $${12}^{o}C$$

Solution

Let increase in the petrol be represented by $$+$$ and decrease in the petrol be represented by $$-$$.
Situation in option (a), (c), (d) represents $$+12$$
SItuation in option (b) represents $$-12$$
Answer B
Question 3
1 / -0

The integer $$5$$ units to the right of $$0$$ on the number line is:

A
$$+5$$

B
$$-5$$

C
$$+4$$

D
$$-4$$

Solution

Option $$A$$ is right.
The integer $$5$$ units to the right of $$0$$ on the number line' is $$0+5$$ $$=+5$$.
Question 4
1 / -0

Subtract $$-134$$ from $$-38$$

A
$$-96$$

B
$$96$$

C
$$-183$$

D
$$183$$

Solution

As per the question : $$-38-(-134)=-38+134=96$$
Question 5
1 / -0

Which of the following is not an integer?

A
$$0$$

B
$$-1$$

C
$$-1.5$$

D
$$1$$

Solution

An integer is a whole number which can be positive negative or zero. the set of integers is denoted by $$Z$$ and defined by
$$Z=\{0,\pm 1,\pm 2,\pm 3\cdots\}$$

So options $$A,B,D$$ all are integers.

And option C which is 1.5 is not an integer.

Hence option $$\textbf C$$ is correct answer.
Question 6
1 / -0

$$(- 35) + (-32)$$ is equal to

A
$$67$$

B
$$-67$$

C
$$-3$$

D
$$3$$

Solution

Now,
$$(-35)+(-32)$$
$$=-35-32$$
$$=-67$$.
Question 7
1 / -0

$$(-29)+5$$ is equal to

A
$$24$$

B
$$34$$

C
$$-34$$

D
$$-24$$

Solution

Let $$(-29)+5=x$$ we can see that $$29$$ has negative sign and $$5$$ has positive sign.
So $$+$$ and $$-$$ will be $$-$$
So $$-29+5=-24$$ because $$24$$ will have sign of $$29$$.

Option (D)
Question 8
1 / -0

Which of the following statement is true?

A
$$- 7 > - 5 $$

B
$$- 7 < - 5 $$

C
$$(- 7) + (- 5) > 0 $$

D
$$(- 7)- (- 5) > 0$$

Solution

We know that,
$$7>5$$
then $$-7<-5$$.
Again,
$$(-7)+(-5)=-7-5=-12<0$$.
And, $$(-7)-(-5)$$
$$=-7+5=-2<0$$.
So option (B) is correct.
Question 9
1 / -0

The successor of $$- 22$$ is

A
$$-23$$

B
$$-21$$

C
$$23$$

D
$$21$$

Solution

The successor of the number $$-22$$ is the number just after it.
And it is $$=-22+1=-21$$.
Question 10
1 / -0

Answer the following using number line.
$$6$$ more than $$- 7$$ is

A
$$1$$

B
$$-1$$

C
$$13$$

D
$$-13$$

Solution

$$-7+6=-1$$
