Answer:
The answer * = 6
Given problem:
What should be placed in place of ( * ) so that 23567*32 will be divisible by 11
Step-by-step explanation:
Given number 23567*32 is divisible by 11
Let * = x
Note:
If the difference of the sum of digits which are in even and odd places is equal or divisible by 11, then that number is divisible by 11.
Now find sum of digits in even place and odd places in given number
⇒ Sum of the digits in odd places = 2+5+7+3 = 17
⇒ Sum of the digits in even places = 3+6+x+2 = 11 +x
assume that difference is equal
Therefore, 17 - 11 - x = 0
6 - x = 0
x = 6
