We require to know the price of each OR since the question is in %, the ratio of all three will also do

(1) The marked price of item B is 75% of the marked price of item A and 200% more than the marked price of item C.
we can get all three in terms of one item so sufficient

(2) The marked price of item A is 400% of the marked price of item C.
Nothing about B

A

Solution of statement I..
B=0.75A=3C
Now we are looking for100*( 0.4A+0.2B+0.1C)/(A+B+C)=(40A+20*0.75A+10*0.25A)/(A+0.75A+0.25A)=(40+15+2.5)/2
A will get cancelled and we will have our answer.

Hi chetan2u ,
You have written B =2C . Shouldn't it be B =3C
C + 200%C = B

Thanks .. you are correct..
Typo..
If it was 200% of C, then it would be 2C
