Question
How many boxes are kept between box X and the box which
contains Pencil? Study the given information and answer the questions: Eight boxes Q, R, S, T, U, V, W and X are placed one above the other but not necessarily in the same order. These boxes contain different stationery items Eraser, Sharpner, Stapler, Push – pin, Fountain pen, Paper clip, Pencil and Colour box but not necessarily in the same order. There are two boxes between Box Q and the box which contains Pencil. Box T is just above the box which contains Sharpner. Two boxes are between boxes S and R, which is below box S. Neither box S nor the box which contains Eraser in bottom four. Box U contains Fountain pen but is not in the bottommost. Box R does not contain Stapler or Colour box. Box S is just above the box which contains Push – pin. The bottommost box does not contain Stapler or Sharpner. Three boxes are between the boxes which contains Eraser and Pencil. Box T is below Box R but not just below. Box R does not contain Pencil. Three boxes are kept between box V and the box which contains Eraser. Not more than two boxes are kept between W and X, which is below box W.Solution
There are two boxes between Box Q and the box which contains Pencil. Three boxes are between the boxes which contains Eraser and Pencil. The box which contains Eraser is not in bottom four. Case1- box Q is above box which contains Pencil and Case2- box Q is below box which contains Pencil.
(iii)- Box T is just above the box which contains Sharpner. Box T is below Box R but not just below. Case1 (b) and Case2 (b) gets eliminated. The bottommost box does not contain Sharpner. Box U contains Fountain pen but is not the bottommost. Box R does not contain Stapler or Colour box. The bottommost box does not contain Stapler. Three boxes are kept between box V and the box which contains Eraser. Case 1(a) –
(iv)- Not more than two boxes are kept between Box W and X, which is below box W. So, case2 (a) gets eliminated. The final arrangement is:
I. 3x6- 19x3+16=0
II. 9y4- 27y2+20=0
I. 63x2 + 148x + 77 = 0
II. 21y2 + 89y + 88 = 0
I. 15/(√x)+9/(√x)=11√x
II. (√y)/4 + (5√y)/12 = 1/(√y)
I. 3p² - 11p + 10 = 0
II. 2q² + 13q + 21 = 0
I. 2y² - 3y – 14 = 0
II. 3x² - 7x + 4 = 0
I. x2 – 10x + 21 = 0
II. y2 + 11y + 28 = 0
I. x= √(20+ √(20+ √(20+ √(20…………….∞)) ) )
II. y= √(5√(5√(5√(5……….∞)) ) )
...I. 2x² - 15x + 13 = 0
II. 3y² - 6y + 3 = 0
I. 3y² - 20y + 25 = 0
II. 3x² - 8x + 5 = 0
I. 40x² + 81x + 35 = 0
II. 63y² + 103y + 42 = 0
