After combining the two statement we get

Area of E = Area of F = Area of A = 20
Now statement 1 gives, Area of D = 40
i.e. Area of B = Area of C = (1/2) Area of E or F = 10

Now we have area of each rectangle hence

SUFFICIENT

Answer:option C

Could you please explain how you got the area of B and C as 10? I did not understand the part where you deduced that the AREA of B=1/2( Area of E or F)

Area of D = 40
Area of A = 20
this indicates that all the rectangle in first row have areas equal to half of areas of rectangle immediately below them because their lengths are the same and width of rectangle in above row is half of that of in immediately below rectangles respectively

that's why area of B and V will be half of area of E and F respectively


I hope this helps!!!

Hi nithinjohn,
Please refer the enclosed diagram, you would notice that
Area of rectangle B=area of rectangle C=z*k

We have x*y=40---(1), x*z=20----(2), and y*k=20 or, k=\(\frac{20}{y}\)---(3)
From (1)&(2),we have z=\(\frac{y}{2}\)

So z*k=(y/2)*(20/y)=10, which is 1/2 times area of E or F

Hope it helps.
