Question 1
1 / -0

Which of the following numbers are divisible by $$2$$?

A
$$10$$

B
$$100$$

C
$$1000$$

D
All of the above

Solution

Since all the options contain an even digit i.e. $$0$$ in the units place,
all the numbers are divisible by $$2$$.

So, option D is correct.
Question 2
1 / -0

The reverse of $$349$$ is

A
$$943$$

B
$$493$$

C
$$394$$

D
None of the above

Solution

Reverse of a 3 digit number means that the digit in the
Hundreds place is put in units place and vice versa.
$$\therefore$$ Reverse of $$349$$ is $$943$$.

So, option A is correct.
Question 3
1 / -0

The expanded form of $$101$$ is

A
$$100+1$$

B
$$99+1$$

C
$$100 \times 1 +1$$

D
None of the above

Solution

The expanded form of:
$$abc = a\times 100 + b\times 10+ c\times 1$$
Here, for $$101$$
$$101 = 100 \times 1 + 0\times 10 + 1\times 1= 1\times100 + 1$$
Question 4
1 / -0

The subtraction of $$349$$ and its reverse is

A
$$594$$

B
$$495$$

C
$$945$$

D
None of the above

Solution

The reverse of $$349$$ is $$943$$
$$\therefore 943 - 349 = 594$$
Question 5
1 / -0

The subtraction of $$999$$ and its reverse is

A
$$0$$

B
$$1$$

C
$$2$$

D
None of the above

Solution

The reverse of $$999$$ is $$999$$
$$\therefore 999 - 999 = 0$$
So, option A is correct.
Question 6
1 / -0

Which of the following numbers are divisible by $$5$$ ?

A
$$10$$

B
$$100$$

C
$$1000$$

D
All of the above

Solution

A number is divisible by $$5$$, if it contains $$0$$ or $$5$$ in the units place.
Since all the numbers have $$0$$ in the units place,
therefore all are divisible by $$5$$.

So, option D is correct.
Question 7
1 / -0

Which of these numbers are divisible by $$2$$?

A
$$1299$$

B
$$2387$$

C
$$2091$$

D
$$3052$$

Solution

We know the divisibility rule for $$2$$:
Always check the last digit end with $$0, 2, 4, 6$$ or $$8$$.
Here, $$3,052$$ is divisible by $$2$$ because the last digit ends with $$2$$.

So, option D is correct.
Question 8
1 / -0

Which of the following numbers are divisible by $$9$$ ?

A
$$81$$

B
$$99$$

C
$$108$$

D
All of the above

Solution

A number is divisible by $$9$$, if the sum of the digits is also divisible by $$9$$.
Sum of digits of $$81$$ is $$8+1=9$$
Sum of digits of $$99$$ is $$9+9=18$$
Sum of digits of $$108$$ is $$1+0+8=9$$
Thus, all given numbers are divisible by $$9$$

So, option D is correct.
Question 9
1 / -0

Which of the following number/s is/are divisible by $$10$$ ?

A
$$10$$

B
$$200$$

C
$$300$$

D
All of the above

Solution

A number is divisible by $$10$$ if it contains a $$0$$ in the units place.
Since all the numbers have $$0$$ in the units place, therefore all are divisible by $$10$$.

So, option $$D$$ is correct.
Question 10
1 / -0

Which of the following numbers are divisible by $$3$$ ?

A
$$12$$

B
$$14$$

C
$$20$$

D
None of the above

Solution

The sum of the digits of $$12$$ is $$1+2 =3$$.
$$3$$ is divisible by $$3$$
Therefore, $$12$$ is divisible by $$3$$.

So, option A is correct.
