Question

what is the value of P when 47P205
in divisible by 3?
​

Answer 1

Answer:

0 or 3 or 6 or 9

Step-by-step explanation:

For a number to be divisible by 3, the sum of its digits has to be divisible by 3

Sum of digits = 4 + 7 + P + 2 + 0 + 5 = P + 18

18 is already divisible by 3, so if P + 18 has to be divisible by 3, P has to be divisible by 3.

Therefore, P can be either 0 or 3 or 6 or 9
