Question 1
1 / -0

Simplify: $$(-4)\times 63 = x \times 21$$.
Find the value of $$x$$.

A
$$-21$$

B
$$12$$

C
$$21$$

D
$$-12$$

Solution

$$X=\dfrac{(-4)\times63}{21}=-12$$
Question 2
1 / -0

Simplify the following :-
$$(-441)\div(21)$$=?

A
$$21$$

B
$$-21$$

C
$$20$$

D
$$-20$$

Solution

$$\dfrac{-441}{21}=-21$$
Hence option $$B$$ is correct.
Question 3
1 / -0

$$-32\times x= 160$$, $$-23\times y= -115$$
What is the value of $$x\div y$$?

A
$$-1$$

B
$$1$$

C
$$-5$$

D
$$5$$

Solution

Given, $$-32\times x=160, -23\times y=-115$$
We have $$x=\dfrac{160}{-32}$$

and $$ y=\dfrac{-115}{-23}=\dfrac{115}{23}$$

Thus $$\dfrac{x}{y}=\dfrac{160\times 23}{-32\times 115}=-\dfrac{32\times23}{32\times 23}=-1$$
Question 4
1 / -0

What is the value of $$x$$ in the following equation?
$$-319\div x =-11$$.

A
$$39$$

B
$$-29$$

C
$$29$$

D
$$-39$$

Solution

We need to find $$x$$ in $$-319\div x=-11$$
$$\dfrac{-319}{x}=-11\\ \Rightarrow x=\dfrac{-319}{-11}=29$$
Question 5
1 / -0

Simplify the following :-
$$\dfrac{39\times(-42)}{(-13)}$$= ?

A
$$-126$$

B
$$14$$

C
$$-14$$

D
$$126$$

Solution

Lets simplift $$\dfrac{39\times (-42)}{-13}$$ as
$$=\dfrac{3\times (-42)}{-1}$$
$$=126$$
Question 6
1 / -0

Compare and put the appropriate sign.
$$-219\;\square 212$$..

A
$$\neq$$

B
$$<$$

C
$$>$$

D
$$=$$

Solution

A positive number is always greater than a negative number.
Thus $$-219<212$$.
Question 7
1 / -0

Compare and put the appropriate sign in the box.
$$-210\;\square-211$$.

A
$$<$$

B
$$>$$

C
$$=$$

D
$$\neq$$

Solution

$$210<211\\ \Rightarrow -210>-211$$ put the negative sign both side, < sign will change to > sign.
Question 8
1 / -0

___________ is a bigger number than any negative integers and smaller number than any positive integers.

A
Four

B
Three

C
One

D
Zero

Solution

Zero is a bigger number than any negative integers and smaller number than any positive integers.
Question 9
1 / -0

Compare and choose the appropriate sign.
$$43,29,52,280$$ $$ \Box$$ $$43,29,25,280$$

A
$$>$$

B
$$<$$

C
$$=$$

D
None of these

Solution

Start comparing with the numbers having greatest place value (from left) till you get an inequality.
$$4=4$$
$$3=3$$
$$2=2$$
$$9=9$$
$$5>2$$
As left value is greater than right value,
the number on the left is greater.
$$\therefore$$ $$43,29,52,280> 43,29,25,280$$
Hence correct answer is option A.
Question 10
1 / -0

What will be the sign of the product if we together multiply $$199$$ negative integers and $$10$$ positive integers?

A
Negative

B
Positive

C
Can't say

D
Data is insufficient

Solution

Multiplication of $$2$$ negative integer result into positive integer.

If we multiply $$199$$ negative integer, then the result will be negative integer

Now if we multiply $$10$$ positive numbers with $$199$$ negative integers

we will get a negative integer because multiplication of negative and positive
integer will always result in negative integer.

Hence option A is correct.
