**Divisibility by 2 :**

All even numbers are divisible by 2.

A number ends with one of the following digits is called as even number.

0, 2, 4, 6 or 8

**Question 1 :**

Which of the following is divisible by 2 ?

(A) 15, (B) 12, (C) 11

**Solution :**

**Options A :**

The unit digit of the number 15 is 5 which is not an even number.

So, 15 is not divisible by 2.

**Options B :**

The unit digit of the number 12 is 2 which is an even number.

So, 12 is divisible by 2.

**Options C :**

Because the unit digit of the number 11 is 1, which is not an even number.

So, 11 is not divisible by 2.

Therefore, the number 12 given in option B is divisible by 2.

**Question 2 :**

Which of the following is divisible by 2 ?

(A) 101, (B) 105, (C) 108

**Solution :**

**Options A :**

The unit digit of the number 101 is 1 which is not an even number.

So, 101 is not divisible by 2.

**Options B :**

The unit digit of the number 105 is 5 which is not an even number.

So, 105 is not divisible by 2.

**Options C :**

Because the unit digit of the number 108 is 8 which is an even number.

So, 108 is divisible by 2.

Therefore, the number 108 given in option C is divisible by 2.

**Question 3 :**

Which of the following numbers must be added to 13 to get a number which is divisible by 2 ?

(A) 0, (B) 1, (C) 2

**Solution :**

13 + 0 = 13

13 + 1 = 14

13 + 2 = 15

In the above calculation, when we add 1 to 13, we get 14 which is an even number.

Because 14 is an even number, it is divisible by 2.

So, option B is correct.

**Questions 4 :**

Which of the following number must be subtracted from 27 to get the two divisible number ?

(A) 0, (B) 2, (C) 3

**Solution :**

27 - 0 = 27

27 - 2 = 25

27 - 3 = 24

In the above calculation, when we subtract 3 from 27, we get 24 which is an even number.

Because 24 is an even number, it is divisible by 2.

So, option C is correct.

**Question 5 :**

Which of the following statements is true ?

(A) All the two digit numbers are divisible by 2

(B) Only two digit even numbers are divisible by 2

(C) All even numbers are divisible by 2

**Solution :**

According to the divisibility rule of 2, all even numbers are divisible by 2.

So, option C is correct.

After having gone through the stuff given above, we hope that the students would have understood, how to check whether a number is evenly divisible by 2.
