1. Each of the questions below consists of a question and two statements numbered I and II are given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and :Give answer a: If the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question. Give answer b: If the data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question. Give answer c: If the data in Statement I alone or in Statement II alone are sufficient to answer the question. Give answer d: If the data in both the Statements I and II are not sufficient to answer the question. Give answer e: If the data in both the Statements I and II together are necessary to answer the question.What is the area of the circle? I. Perimeter of the circle is 88 cms. II.

II : Diameter = $$28$$ cm => Radius, $$r=frac{28}{2}=14$$ cm Thus, area = $$pi r^2$$ = $$frac{22}{7} imes(14)^2=616$$ $$cm^2$$ Thus, statement II alone is sufficient. $$ herefore$$ Either statement alone is sufficient. => Ans - (C)
