In questions a question is followed by data in the form of two statements labelled as I and II. You must decide whether the data given in the statements are sufficient to answer the questions. Using the data make an appropriate choice from (a) to (d) as per the following guidelines :

I. The radii of the two circles are equal.
II. The distance between their centres is 12 cms.

I. A’s capital is ₹ 5,000 more than that of B.
II. A and B are the only partners in the business.
For two sets A and B, what is $$n(A \cap B)$$ ?
I. n(A) = 6 and n(B - A) = 8
II. n(A - B) = 8 = n(B - A) and $$n(A \cup B) = 24$$
If ‘a’ is a positive integer, is it a prime number ?
I. It is odd number,
II. It is an even integer greater than 2.
If x and y are real numbers, what is the value of xy?
I. x + y = 16
II. $$x^2 + y^2 = 160$$
What is the value of $$\sin (2 \theta)$$ ?
I. $$tan \theta + \cot \theta = 3$$
II. $$(\cosec \theta + \cot \theta)(\cosec \theta - \cot \theta) = 1$$
