Suppose that https://latex.artofproblemsolving.com/8/4/0/8404d0f21e5ca94dbbe3d87a297dacb949babad8.png where \(P, Q, and b \) represent three distinct digits 1-9. If \(Q=\frac{P}{2}\), and \(P\) is two less than \(b\), what is the value digit of \(P\)?

Try this:

P = 4 and Q =4/2 =2, and b =P+2 = 4 + 2 =6. So you have:

P = 4

Q = 2

b = 6. But P(6) x P(6) =QP(6) =4(6) x 4(6) =24(6)
