Question

if the number 7713A8 is divisible by 4, where A is a digit , what will be the one of the possible value of A?

Answer 1

Divisibility of 4 =Last two numbers should be divisible by 4

so given number is 7713a8

only if we keep a=4,a=8

the number will be divisibled by 4

a=4 771348 last two numbers sum is 12 so it is divisible

a=8 771388 sumof last two numbers is 16 is divisible

Answer 2

The one of the possible value of A is 4

Correct question : If the number 7713A8 is divisible by 4, where A is a digit, one of the possible value of A is (a) 4 (b) 3 (c) 7 (d) 5

Given :

The number 7713A8 is divisible by 4, where A is a digit

To find :

One of the possible value of A is

(a) 4

(b) 3

(c) 7

(d) 5

Concept :

Divisibility rule of 4 :

A number is divisible by 4 if the last two digits of the number are divisible by 4.

Solution :

Step 1 of 2 :

Write down the given number

Here the given number is 7713A8

where A is a digit

Step 2 of 2 :

Find one of the possible value of A

Here it is given that 7713A8 is divisible by 4

Now divisibility rule of 4 states that if a number is divisible by 4 if the last two digits of the number are divisible by 4.

Since 7713A8 is divisible by 4

⇒ A8 is divisible by 4

Which hold when A = 0 , 2 , 4 , 6 , 8

So the the possible values of A are 0 , 2 , 4 , 6 , 8

Hence the correct option is (a) 4
