The seven finalists of 'Variety Dog Pet Show' are made to stand on the podium for their final round. Each
participant has a different breed of dog as his/her entrant. The number of participants to the right of Ana is
twice of that of Cindy and they are standing next to each other. The owner of the Alsatian is a neighbour of
the owner of the Bulldog and Britney, who is standing at one of the extreme ends. Pixy, who owns a Poodle
is at the middlemost position. The Labrador and the Alsatian dogs are kept as far as possible and neither
of them has the Dalmatian as its neighbour. Ana and Danny are the neighbours of the owner of the German
Shephard. Either Mitch owns a Doberman or Laila doesn't own an Alsatian.
9. Who is the owner of the Dalmatian?
A. Danny B. Ana C. Cindy D. None of the above
10. If Mitch and Cindy interchange their positions, who is standing second to the left of the owner of the
Doberman?
A. Poodle B. Bulldog C. Laila D. None of the above

(32+25+27)/2 - 32 = 10.

A person drew 'x' triangles on a board such that no two of them touched or intersected each other.
His friend counted the various types of triangles on the board and came up with the following data.
• Exactly 20 triangles were there in which all the sides were equal.
• At least 32 triangles were there in which at least two sides were equal.
• Exactly 12 triangles were there in which all the sides were of different lengths.
• Exactly 24 triangles were there in which one interior angle was obtuse.
• Exactly 28 triangles were there in which all the interior angles were acute.

What is the least possible value of 'x'?
(a) 52
(b) 44
(c) 96
(d) None of these

Pu + Pl = 32
C + Pl = 27
C + Pu = 25

C + Pu + Pl = 42
(C, Pu, Pl) = (10, 15, 17)

ABCD is a parallelogram and P is a point on the plane such that area of triangle ABP is 10 and that of triangle CPD is 20. Find the maximum and minimum possible area of parallelogram ABCD.

Car= x-32
Plane=x-25
Puzzle=x-27
Therefore,
x-32 + x-25 + x-27= x
3x-84=x
x=42. So, Cars= 42-32=10

c+pu=25
pl+pu=32
pl+c=27
c=10
