Question

Given no 1372 x 413 is divisible by 11 where is x is a digit find the value of x

Answer 1

Answer:-

3

Step-by-step explanation:-

The sum of the odd-place digits

= 1+7+x+1 = x+9

Sum of even-place digits

= 3+2+4+3 = 12

difference :

x+9 - 12 = 0

x = 3

Answer 2

we know the divisibility rule for 11

that is, sum of odd digits - sum of even digits of a number should be divisible by 11

According to the Question,

(1+7+x+1) - (3+2+4+3)

(9+x)- 12 should be divisible by 11

finding values of x

Let difference of odd and even digits be 0

-3+x= 0

x=3

Let difference of odd and even digits be 11

-3+x=11

x=14

Since, x is a digit number, so, x cannot be 14

Therefore x=3

hope it helps :)
