Complete the above grid such that:
 Each of the letters K to Z represents a different integer from 1 to 16.
 Each of the columns, each of the rows and each of the main diagonals equals A.
 Each of the 16 letters from K to Z is repeated precisely four times in the above grid.
 A = P*T + R
 Z = 2*R
 N = V/3
 T = Y  (N + K)
 U = S + L
 M*Q + O + K = W + X
A=68, But rest is not logically solvable. Only trial and error.
R=2,3,5,8 and Z=4,6,10,16
P/T= 5,6,7,9,11,12,13
Rest of solution is trial and error. Any Hint?
