1. If 55055 + x = 55555

   x = 500

   then,

   55,555 - 100x = 55,555 - 50000

   = 5555

   Ans : C

2. [(3y²) x²]4

   = (3y²)4 (x² )4 [Using law of indices (xm)ⁿ = x^mn ]

   = 34y⁸x⁸

   = 81y⁸x⁸

    

   Ans : D

3. 

   Ans : B

4. Let the radius of the circle be r.

   Let the side of the square be x.

   Area of circle = p r²

   Area of squares = x²

   p r² = x²

   Since x² = 4

   p r² = 4

   r =
   C = 2 p r

   = 2 p ´

   = 4 Ö p

   Ans : A
