Show answer & explanation
Correct answer: D
Explanation
Given:
Number = 39P6, divisible by 3.
According to the formula:
If the sum of the digits of a number is divisible by 3, then the number itself is divisible by 3.
Sum of digits = 3 + 9 + P + 6 = 18 + P
18 is divisible by 3.
Therefore, P must also be divisible by 3.
Possible values of P = 0, 3, 6, 9
