Question: Each question is followed by two statements, A and B. Answer each question using the following instructions
Choose 1 if the question can be answered by using one of the statements alone but not by using the other statement alone.
Choose 2 if the question can be answered by using either of the statements alone.
Choose 3 if the question can be answered by using both statements together but not by either statement alone.
Choose 4 if the question cannot be answered on the basis of the two statements.
AB is a chord of a circle. AB = 5 cm. A tangent parallel to AB touches the minor arc AB at E. What is the radius of the circle?
A. AB is not a diameter of the circle
B. The distance between AB and the tangent at E is 5 cm
Let radius of circle be r.
AC = 2.5 as radius bisects the chord.
We have been told that AB is not a diameter of the circle. But it does not give us any useful information to solve the problem.
So, statement A alone is not sufficient to answer the question.
So, statement B alone is sufficient to answer the question.
Hence, option (a).
