    Miguel: 500 out of 750 students have part time jobs.

    500 : 250 = 2

    750 : 250 = 3

    500:750 = 2:3

    A) 200 out of 300 ⇒ 200/100 and 300/100 ⇒ 2:3

    B) 700 out of 1100 ⇒ 700/100 and 1100/100 ⇒ 7:11

    C) 800 out of 1200 ⇒ 800/400 and 1200/400 ⇒ 2:3

    D) 9000 out of 1300 ⇒ 9000/100 and 1300/100 ⇒ 90:13

    Among the choices, Choice B could represent Kureshi's Data because it is not proportional to the data of Miguel.

    Choice D is not possible. You cannot have a result that is way beyond the scope of your population. It is impossible to get 9000 students out of only 1300 students.
