### Answers and Explanations

**Answer 1: (c)**

The value of history books = Rs 14.6 lakh

The value of film magazines = Rs 3.92 lakh

Hence the required percentage = {(14.6 – 3.92)/3.92}x100 = 272.4%

The correct answer is option(c)

**Answer 2: (c)**

As the data is given about the value of the books and not about their numbers, so the statements (a) and (b) need not to be true. But the value of sports magazines is higher than that of geography books as can be seen from the table. Thus, (c) is the correct option.

**Answer 3: (a)**

The Value of the literature books = Rs29.2 lakh and the total investment in books and magazine section = 146 + 28 = Rs174 lakh

So the required percentage = (29.2/174) x 100 = 16.78%

The correct option is (a)

**Answer 4: (b)**

The total investment in books and magazine section = 146 + 28 = Rs 174 lakh

The total value of science material = 20.44 + 3.08 = Rs 23.52 lakh

The required percentage = (23.52/174)x 100 = 13.52%

The correct option is (b)
