Question
An 11-digit number 7823326867X is divisible by 18 What
is the value of X?Solution
To check the divisibility by 18 we must check divisibility by 2 and 9. 7+8+2+3+3+2+6+8+6+7+ x = 52 + x Now Putting x = 6, 4, 8, 2 We have, 52+ 6 = 58 52+4= 56 52+8= 60 52+2= 54 We can see 54 is divided by both 2 and 9. So X=2
