Question

Given that the numbers 60AB57377 is divisible by 11, where A and B are digits. Find the possible value of A and B.

Answer 1

Answer:

Thus possible values of A and B are (9,5), (8.4), (7,3), (6,2), (5,1)

Step-by-step explanation:

Rule: Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number.

  6-0+A-B +5 -7 +3 -7 +7 = 7 +  A - B

7+A-B should be divisible by 11 for the number to be divisible by 11.

7+A-B = 11

=> A-B = 4

Thus possible values of A,B are (9,5), (8.4), (7,3), (6,2), (5,1)
