The following arrangement consists of an ideal transformer and an attenuator which attenuates by a factor of $0.8.$ An ac voltage $V_{WX1} = 100V$ is applied across $WX$ to get an open circuit voltage $V_{YZ1}$ across $YZ.$ Next, an ac voltage $V_{YZ2}= 100V$ is applied across $YZ$ to get an open circuit voltage $V_{WX2}$ across $WX.$ Then $,V_{YZ1}/V_{WX1},V_{WX2}/V_{YZ2}$ are respectively, 

  1. $125/100$ and $80/100$
  2. $100/100$ and $80/100$
  3. $100/100$ and $100/100$ 
  4. $80/100$ and $80/100$
