The sum of x% of y and y% of z is z% of x.
x and y are integers such that 1 = < x = < 9, 1 = < z = < 9.
If y is a perfect square number then how many ordered pair ( x , z ) are possible satisfying the given condition.

x, y, z and k are four non zero positive integers satisfying 1/x + y/2 = z/3 + 4/k, minimum integral value of k for integral value of x, y and z will be
