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)
