answer is b

According to equimarginal principle the MArginal utility of money must be same. So MUm of good x: 30/10=3. It must be the same for good Y too. Initially, when price was 30, MUm=MU1/P= MU1/30. From here MU1= 30*3=90. When price fell to 20 MU2=20*3=60. So change in MU=MU1-MU2= 30. From graph we can see, 30 utils=10 units. So, ans is B.

Could you go through my doubt too above? :)
