A rectangle is divided into four rectangles with area 70,36,20 and X. The value of X is:

• 70/x = 36/20
  => x*36= 20*70
  => x= 20*70/36 = 350/9

• 70:20=36:x
  => x = 36*20/70 = 72/7

• 70*20-36X=0
  1400=36X
  X=350/9

• Let us take most simple case of rectangles of 70x1 , 36x1 ,20x1 and Xx1 to make rectangle of 70x2 Then,
  
  |-----70---------|
  |-20-|---36--|-X-|
  
  so X = 70- (20 + 36) = 24 Ans

• 70/x = 36/20
  => x*36= 20*70
  => x= 20*70/36 = 350/9
  350/9 is the correct option

• ans=13
  36*2-70=2;
  20*2-36=4;
  similarly,
  13*2-20=6
  ans is the multiple of 2 i.e 2n,where n is an integer

• 70/x = 36/20
  x=20*70/36
  x=1400/36 (go with 4 Multiples 350*4=1400 and 9*4=36)
  x=350/9

• Areas are in proportion.
  (70/x) = (36/20)
  
  ⇒
  
  x = 350/9
