A bookseller sold 'a' number of Geography textbooks at the rate of Rs. x per book, 'a + 2' number of History textbooks at the rate of Rs. (x + 2) per book and 'a - 2' number of Mathematics textbooks at the rate of Rs. (x - 2) per book. What is his total sale in Rs.?

A. 3x + 3a

B. 3ax + 8

C. 9ax

D. x3 a3

Answer

Sales = Number of textbooks × Rate

Sale of Geography textbooks = ax

Sale of History textbooks = (a+2)(x+2) = ax + 2a + 2x + 4

Sale of Mathematics textbooks = (a - 2)(x - 2) = ax - 2x - 2a + 4

Sale of all books = 3ax + 8

The correct option is B.
