Answer 1

Answer:

The number 23A4534A01 is divisible by 11. How many values can “A” be substituted with?

A. 1

B. 4

C. 9

D. 10

E. Infinite

Answer 2

Answer:

10

Step-by-step explanation:

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.

following through the divisibility of 11, we would say that (2+x+5+4+0)-(3+4+3+x+1)=0 and the number will always be divisible by 11 no matter whatever x takes. Now x can take only numbers between 0-9 and hence the answer is 10
