Consider the number, N 5768PO2Q
If P = 2 and the number N is divisible by 3, them find number of possible values of Q.

Text Solution

Verified by Experts

The number is divisible by 3 iff 5+7+6+8+P+0+2+Q=a multiple of 3.
`implies` 28+2+Q is multiple of 3. So,Q=0,3,6,9
So, 4 values of Q are possible.
