Unless and until mentioned ,
CPIideal pipeline(without stalls) = 1
The given CPI of 1.4 is for non pipelined processor not the pipelined one..So it would be wrong to consider it for pipelined system..
Now we calculate no of stall cycles / instruction = 0.2 * 1 + 0.05 * 2
= 0.3
So CPI for the modified pipelined system i.e. with stalls = 1 + 0.3
= 1.3
Hence the correct answer should be 1.3
