Each of these questions has a problem and two statements, number I and II. Decide if the information given in the statement is sufficient for answering the problem. Mark the answer as

Question 116

If a rectangle has length $$a$$ and width $$b$$, what is its area
I. $$2 a = \frac{15}{b}$$
II. $$a = 2 b - 2$$

Solution

Length of rectangle = $$a$$ and Width = $$b$$, => Area = $$ab$$

Statement I : $$2 a = \frac{15}{b}$$

=> $$ab=\frac{15}{2}=7.5$$

Area of rectangle is 7.5, hence statement I alone is sufficient.

Statement II : $$a = 2 b - 2$$

Since, there are no specific values of $$a$$ and $$b$$, we cannot find the area, hence statement II alone is not sufficient.

=> Ans - (A)
