Statement I
2D = C
2C = B
A+B+C+D+blank = 1600
We dont know anything about the blank block. Insufficient.

Statement II
A = 800
we have no relation of A to B, D or C. Insufficient.

Combining I & II
We dont have any relation between A and B or D or C.
We also dont know about the blank box.
Insufficient.

Hence E.

[nishit.shah]

We do have a relation between A and rest of the blocks

Total area : 1600

Area apart from A is : 1600-800 = 800

But problem is there are two unknown, if you consider area of B as x

than B+D+C = x + 0.5x +0.25x

and B+D+C+ Blank = 800

Hence two unknown and one equation, cant solve


Answer E
