Given that log⁡xy,log⁡zx,log⁡yz\log _x y, \log _z x, \log _y z are in GP, xyz=64x y z=64 and x3x^3, y3,z3y^3, z^3 are in A.P. Which one of the following is correct? xy,yzx y, y z and zxz x are

Options

  1. Ain AP only
  2. Bin GP only
  3. Cin both AP and GP
  4. Dneither in AP nor in GP

Correct answer

C. in both AP and GP

Step-by-step solution

Similarly xy,yz,zxx y, y z, z x are also in A.P. and G.P. both.
