Ans: E


2. Given a two figrures, first figure contains a square with a circle of radius of the circle is 'r' inscribed in it and the area outside the circle(within the square) is shaded . Second figure contains a circle radius of 'r' with a square inscribed in it and the area outside
the square(within the circle) is shaded.
Col A: Area of Shaded region in the first figure
Col B: Area of Shaded region in the Second figure


3. If 2n+1 is the median of seven consecutive integers . What is the mean of the integers?

I don't think its answer is A, the side opposite to angle Q is PR whose length is 13 and for angle Q to be greater then 90 (obtuse angle) the following identity should be true:
13^2 > 12^2 + 7^2

What do you say ?


9. Given 6 symbols...... * , * , ? , ? , ? , $. How number of codes that can be formed from left to right using these 6 symbols... such that repeation is not allowed?



10.There was a ladder given. The ladder is of length 5 and it is displaced i.e slanted downwards such that it falls 'x'mts in height and its horizontal length increases by 'y'mts.
Col A: x
Col B: y


11. M^2 = 4^x+4^x+4^x+4^x. What is the value of M?
