Question 1
1 / -0

An integer which is not divisible by 2 is called a/an

A
even number

B
odd number

C
prime number

D
composite number

Solution

All the even numbers are divisible by 2. The integers which are not divisible by 2 are called odd numbers, e.g 1, 3, 5, 7 etc.
Question 2
1 / -0

Directions For Questions

Given:
$$\quad\quad\quad$$ B A N A
$$\quad\quad+$$ N A N A
$$\quad\quad\quad -----$$
$$\quad\quad$$ Q B P B
$$\quad\quad\quad -----$$

where, $$A = 3$$ and $$Q = 8$$.

...view full instructions

The value of $$2$$B is

A
$$12$$

B
$$42$$

C
$$32$$

D
$$16$$

Solution

$$\quad\quad\quad$$ B 3 N 3
$$\quad\quad+$$ N 3 N 3
$$\quad\quad\quad ----$$
$$\quad\quad$$ 8 B P B
$$\quad\quad\quad ----$$
Here
A $$= 3$$ and Q $$= 8$$
As, $$3 + 3 = $$ B $$ = 6$$,
N $$= 8 -$$ B $$= 8 - 6 = 2$$,
So, P $$=$$ N $$+$$ N $$= 4$$.
$$2$$B $$=2\times 6 = 12$$
Question 3
1 / -0

$$Addend + addend = ..........$$

A
product

B
difference

C
sum

D
quotient

Solution

$$\Rightarrow$$ $$Addend+Addend=Sum$$
$$\Rightarrow$$ $$Addend$$ means any group of number added together to form a sum.
$$\Rightarrow$$ For example : $$3+5=8$$,
$$\Rightarrow$$ Here, $$3$$ and $$5$$ are addend and $$8$$ is a sum.
Question 4
1 / -0

Expanded form of 27012 is:

A
$$2000+700+0+10+2$$

B
$$20000+700+0+10+2$$

C
$$20000+1000+0+70+2$$

D
$$20000+7000+0+10+2$$

Solution

The general form of five digits number $$abcde$$ will be,
$$abcde = a \times 10000 + b \times 1000 + c \times 100 + d \times 10 +e$$
$$27012=2\times 10000+7\times 1000+0+1\times 10+2$$
Therefore, $$27012=20000+7000+0+10+2$$
Question 5
1 / -0

Express the given number in the expanded form: $$108$$

A
$$(100 \times 1 )+ 8$$

B
$$100 + 1 \times 8$$

C
$$10 \times 1 + 8$$

D
None of these
Question 6
1 / -0

The numbers which are multiples of 2 are called

A
odd

B
prime

C
composite

D
none of these

Solution

The numbers which are multiples of 2 are called even number.
Ex-$$2,4,6,8,10$$ etc.
All these numbers are divisible by $$2$$.
Question 7
1 / -0

If a number is divisible by 9, then it is also divisible by which number?

A
3

B
6

C
2

D
None of these

Solution

If a number is divisible by $$ 9 $$, then it is also divisible by $$ 3 $$ as $$ 9 = 3 \times 3 $$
Question 8
1 / -0

Which of the following numbers are not divisible by $$5$$?
$$30,49,75,210,305$$

A
$$30$$

B
$$49$$

C
$$75$$

D
$$210$$

Solution

Given list of numbers are $$30, 49, 75, 210, 305$$
Numbers ending in either $$5$$ or $$0$$ are divisible by $$5$$.
Hence, $$49$$ is not divisible by $$5$$.
Question 9
1 / -0

Which list shows the first five multiples of $$2$$?

A
$$2, 3, 4, 5, 6$$

B
$$2, 4, 6, 8, 10$$

C
$$2, 20, 200, 2,000, 20,000$$

D
$$2, 22, 222, 2,222, 22,222$$

Solution

The first $$5$$ multiples of $$2$$ are as follows,
$$2×1=2$$
$$2×2=4$$
$$2×3=6$$
$$2×4=8$$
$$2×5=10$$

Option B has the desired list.
So option B is the correct answer.
Question 10
1 / -0

The expanded form of $$72$$ is

A
$$10 \times 7+2$$

B
$$10\times8-8$$

C
$$70+2$$

D
None of the above

Solution

The general form of two digits number will be, $$ab= a \times 10 + b $$
So, $$72 = 10 \times 7 + 2$$

Hence, $$Op-A$$
