Question 1
1 / -0

Encircle the odd one of the following

A
$$(-\mathbf{4},\mathbf{1})$$

B
$$(-\mathbf{5},+\mathbf{2})$$

C
$$(-\mathbf{4},+\mathbf{1})$$

D
$$(-9,+7)$$

Solution

Option (d) is correct.
(a) $$-4+1=-3$$
(b) $$-5+2=-3$$
(c) $$-4+1=-3$$
(d) $$-9+7=-2$$

By the above calculation, we can see that option d gives -2 while other options give -3. Thus, option d is different from all others.
Question 2
1 / -0

Encircle the odd one of the following

A
(-3,3)

B
(-5,5)

C
(-6,1)

D
(-8,8)

Solution

Option (c) is correct.
(a) $$-3+3=0$$
(b) $$-5+5=0$$
(c) $$-6+1=-5$$
(d) $$-8+8=0$$

By the above calculation, we can see that option c gives $$-5$$ while other options give $$0$$. Thus, option $$c$$ is different from all others.
Question 3
1 / -0

If $$\otimes, O,\oslash$$ and represent some integers on the number line, then descending order of these numbers is

A
$$\cdot, \otimes, \oslash, O$$

B
$$\otimes, \cdot, \oslash, O$$

C
$$O, \oslash, 8, \cdot $$

D
$$O, \cdot, \otimes, \oslash$$

Solution

Option (c) $$O, \oslash, 8, \cdot $$
is correct; the symbol has a larger value that will be written first, hence, is in descending order.
Question 4
1 / -0

Which of the following is not the additive inverse of a?

A
$$-(-a)$$

B
$$a \times(-1)$$

C
$$-a$$

D
$$a \div(-1)$$

Solution

Option (a) is correct.The additive inverse of a is a. Hence, $$-(-a)$$ is not correct.
Question 5
1 / -0

The value of $$5 \div(-1)$$ does not lie between

A
0 and 10

B
0 and 10

C
4 and 15

D
6 and 6

Solution

Option (b) is correct. Since, $$\dfrac{5}{(-1)} = -5 $$ . Hence,-5 does not lie between 0 and 10.
Question 6
1 / -0

By observing the above number line, state which of the following statements is true.

A
B is 2

B
A is 4

C
B is –13

D
B is $$- 4$$

Solution

From above number line we cans see that $$A$$ is $$7$$ marks right of $$0$$ and $$B$$ is $$4$$ marks to the left of $$0$$
So, $$A=7$$ and $$B=-4$$
Hence, Option $$(D)$$ is correct
Question 7
1 / -0

Sum of two negative integers is

A
negative

B
positive

C
zero

D
infinite

Solution

Negative
$$\because$$$$-1+(-2)=-1-2=-3$$
Question 8
1 / -0

The integer which is $$2$$ more than $$(-7 +(-2))$$ is ________.

A
$$-7$$

B
$$-9$$

C
$$11$$

D
$$-3$$

Solution
Question 9
1 / -0

In a list of $$37$$ consecutive integers, the median is $$70$$. What is the largest integer in the list?

A
$$96$$

B
$$97$$

C
$$98$$

D
$$99$$
Question 10
1 / -0

Every positive integer is ______ than every negative integer.

A
Greater

B
Smaller

C
