Question

There are 18a${}^2$ + 24ab students in a class. If they are sitting in '6a' rows, how many students are there in a row?

• A. 3a
• B. 4b
• C. 1
• D. 3a + 4b

Answer 1

The correct option is D 3a + 4b

Total number of students in the class
= 18a${}^2$ + 24ab
Number of rows = 6a
Number of students in each row
= (18a${}^2$ + 24ab) $÷$ 6a
= 6a(3a + 4b) $÷$ 6a
= 3a + 4b
