So,folks here are the correct answers

Analogy Question
The correct answer is D.
The second of the two verbs adds sinister overtones to the action of the first-_wait : lurk. Move_ and skulk (to move in a stealthy manner) are similarly related.
Problem Solving
The correct answer is C.
Let the side of the square be 'a'
Area of the square = a2
Area of the rectangle =2a
2
(a+8)(a) = 2 a^2
a = 8
Hence perimeter of the square = 4×8 = 32 cm

    Quantitative Ability Option C : 32cm

    Area of Rectangle whose length is ‘l’cm and breadth is ‘b’cm is = lb cm2. Area of a square whose side is ‘x’ is= x2 cm2.

    Area of rectangle = 2 Area of Square lb = 2 (x2) -(i) Since length of rectangle is 8 cm greater than side of square, therefore, l=x+8. It is given that breadth of rectangle is equal to the side of the square, therefore,b=x.

    Putting values of l and b in equation (i), (x+8)x = 2(x2) x2 + 8x = 2(x2) 8x = x2 x=8

    So, Perimeter Of Square = 4x =4*8=32 cm.
