Solution :

a). Bundles
= U ( _____ , 2), lie on the same indifference curve. Suppose missing numbers is x.
So, 
(40 x 5) + (2 x 5) = 50x + (2 x 2)
210 - 4 = 5x

So Alexander has
apples and
bananas. The indifference curve though
also include bundle.
Therefore, (41.2, 2)
b). 


= 0.4
So Alexander has
apples and
bananas with this bundle. Alexander would like to give up
unit apples for a banana.
