Please help me in calculating the TCPI

For your project, find the to-complete performance index (TCPI) based on the given data:
Budget at completion of the project = 700,000
Cost variance of the project = 25,000
Earned value of the project = 200,000
Estimate to Complete has now been revised to 425,000
 
  Choice 1  0.9   
  Choice 2  1.176 
  Choice 3  1.5  
  Choice 4  -1.5

Thanks
