Question 1
1 / -0

Choose the correct statement from following:

A
$$8,58,68,788 > 8,58,78,688 > 8,58,88,687$$

B
$$8,58,78,688 > 8,58,68,788 > 8,58,88,687$$

C
$$8,58,68,788 > 8,58,88,687 > 8,58,78,688$$

D
$$8,58,88,687 > 8,58,78,688 > 8,58,68,788$$

Solution

Clearly the first $$3-$$digits of each number are same.
So, let us compare rest of the remaining $$5-$$digits of each number.
For option $$\text{A}$$, we have
$$68788,78688,88687$$
Clearly, $$88687>78688>68788$$
So, option $$\text{A}$$ is wrong.
Now, check for option $$\text{D}$$
We have, $$88687, 78688, 68788$$
Clearly, $$88687>78688>68788$$$$
So, option $$\text{D}$$ is correct.
Question 2
1 / -0

The identity elements with respect to addition in integers is

A
$$1$$

B
$$-1$$

C
$$0$$

D
none

Solution

Any mathematical object that ,when applied by an operation ,such as addition and multiplication ,to another mathematical object ,such as numbers , leaves the another object unchanged is called an identity object.
The identity element with respect to addition in integers is '$$0$$'.
Question 3
1 / -0

Solve: $${(-12)\times (-3) \times 4\times (-6) =}$$ ?

A
$$-144$$

B
$$-908$$

C
$$+864$$

D
$$-864$$

Solution

$$(−12)×(−3)×4×(−6)=(36)\times 4\times (-6)\\ =144\times (-6)\\ =-864$$
Question 4
1 / -0

Suppose we represent the distance above the ground by a positive integer and that below the ground by a negative integer, then answer the following:
An elevator descends into a mine shaft at the rate of $$5\text{ m/min}$$. What will be its position after one hour?

A
$$250$$

B
$$200$$

C
$$100$$

D
None of these

Solution

Since, the elevator going down, so the distance covered by it will be represented by a negative integer.
Change in position of elevator in one minute $$=$$ $$-5 \text{ m}$$

Position of the elevator after $$60$$ minutes $$=$$ $$(-5)\times 60$$
$$ =-300\ \text{ m}$$

That means the position of the elevator will be $$ 300\text{ m}$$ below ground level.
Question 5
1 / -0

Sign of the product of 231 negative integer and 9 positive integer is

A
Negative

B
Positive

C
0

D
None of these

Solution

We know that the product of two integers with unlike signs (two integers, one with positive sign and one with negative sign) is always negative.

The given two integers are $$-231$$ and $$+9$$ and the product of these integers is:

$$(-231)\times (+9)=-(231\times 9)=-2079$$ which is a negative integer.

Hence, sign of the product of the given integers is negative.
Question 6
1 / -0

Evaluate:
$$\displaystyle (148)\div (-4)\quad $$

A
+37

B
-37

C
-38

D
None of these

Solution

$$(148)\div(-4)=-148\div4=-37$$
Question 7
1 / -0

$$\displaystyle (-24)\times (-2)\times (-2)\times 0\times (-4) =$$

A
$$+384$$

B
$$-384$$

C
$$0$$

D
None of these

Solution

$$\displaystyle (-24)\times (-2)\times (-2)\times 0\times (-4)
= +48\times 0\times -4
=0\times -4
=0 $$
Question 8
1 / -0

Product of two integers is - 48. lf one of the integers is - 6, then the other is ...........

A
1

B
288

C
0

D
8

Solution
Question 9
1 / -0

$$\displaystyle (-8)\times (-2)\times (+3)\times (-4) = $$

A
$$+192$$

B
$$-192$$

C
$$+28$$

D
$$-4$$

Solution

$$ (-8)\times (-2)\times (+3)\times (-4)$$
$$= +16\times -12$$
$$= -192 $$
Question 10
1 / -0

Check whether closure property is verified for integers for the given operation:$$(-50)-(-20)=-30$$

A
This is commutative property

B
This is associative property

C
Integers are closed under addition

D
Integers are closed under subtraction

Solution

$$-50$$ is an integer and $$-20$$ is also an integer.
$$-50-(-20)=-30$$, which is an integer.
Hence given Integers are closed under subtraction.
