Hi Ayushya.. :)

2011: Question is silent on whether we're plotting on (Y,r) space or (Y,i) space and we're asked to find what happens to the LM curve.

Now, we know LM is a function of nominal interest rate(i). So, will assume we're plotting on (Y,i) space. Hence, any change in expected inflation rate will have no impact on LM curve.

2009: We're asked to find what happens to the real interest rate. So, will plot in (Y,r) space. Now, an increase in expected inflation rate will have no impact on IS curve but will shift the LM curve on the right. Hence, an increase in income level and a decrease in real interest rate.
