Question

given that the no 148101a095 is divisible by 11,where a is a digit.what are the possible value of a​

Answer 1

4 or 9 can be at the place of a.

Answer 2

The possible value of a is 4.

Step-by-step explanation:

Given : Number 148101a095 is divisible by 11, where a is a digit.

To find : What are the possible value of a​ ?

Solution :

According to the divisibility rule of 11,

We must subtract and then add the digits in an alternating pattern from left to right. If the answer is 0 or 11, then the result is divisible by 11.

Taking first alternative terms,

$S_1=1+8+0+a+9$

$S_1=18+a$

Taking second alternative terms,

$S_2=4+1+1+0+5$

$S_2=11$

Now subtract,

$S_1-S_2=18+a-11=7+a$

So, 7+a is divisible by 11 we check on different values of a

If a=1, 7+1=8 not divisible by 11

If a=2, 7+2=9 not divisible by 11

If a=3, 7+3=10 not divisible by 11

If a=4, 7+4=11 is divisible by 11

Therefore, the possible value of a is 4.
