EAC = BAC / Cumulative CPI
       = 270000 / 1.06
       = 254716.98
      
Answer is 4. (none of the above)

Respected Pawarji Sir,


 


Maths is totally an unknown territory till now. Let me get little comfortable on this first and then will answer you.

BAC = 270000


AC = 100000


CPI = 0.9


EV=CPI * AC = 90000


NEW CPI = 1.06


EAC=AC+((BAC-EV)/CPI)


100000+(270000-90000)/1.06= 269811


270000 APPROX


B?

First time, I am seeing this formula. So we need to understand the scenario and have to apply respective ETC.


EAC=AC + ( (BAC-EV) / CPI)


Is the anser 'B' correct one ?

Its derivation of


your known formula


TCPI = (BAC-EV)/(EAC-AC)


In question TCPI is written as new CPI


EAC-AC = (BAC-EV)/CPInew


EAC = ((BAC-EV)/CPI) +AC


CPI1st =EV/AC


EV = 100000X0.90(1ST CPI) = 90000


={(270000-90000)/1.06} +100000


= (180000/1.06) +100000


= 169811 +100000


= 269811 ~27000

Thank you, Pawar.   From this, I clearly understood the formula  and idenfied some gaps on my EVM. 
 


Your reply really helps me  and Thanks to this forum also.
