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
If x, y, z are 3 non zero positive integers such that x+y+z = 8 and xy+yz+zx = 20, then What would be minimum possible value of x*y^2*z^2
x and y are distinct 2 digit numbers such that y is obtained by reversing the digits of x. Suppose they also satisfy x^2 - y^2 = m^2 for some positive integer m, then find the value of x+y+m?
