If 6428A83 is divisible by 9, then the value of A is equal to :
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 5.
A number is divisible by 9 if the sum of its digits is divisible by 9.
The given number = 6428A83
Sum the digits = 6 + 4 + 2 + 8 + A + 8 + 3 = 31 + A
So, (31 + A) is divisible by 9
If A = 5, then, 31 + A = 31 + 5 = 36 (Divisible by 9)
Therefore, the value of A is 5.
