Question

Write a digit in the blank space of the following number so that the number formed is divisible by 11 43__230

Answer 1

Answer:

9

Step-by-step explanation:

Divisibility rule of 11= the difference of the sum of the alternative digits should be divisible by 11

So

Let the missing digit be 'x'

(4+x+3) - (3+2+0) = no. divisible by 11

7+x - 5 = no. divisible by 11

x+2= no. divisible by 11

By applying trial and error method,

9+2= 11

So the value of the missing digit can be 9

Verification:

(4+9+3) - (3+2+0)

= 16-5

= 11
