      the ratio 9:7. If the number of students in the first department was 27 less and in the second department 21 more, both would have equal students. Find the original number of students in the second department.

      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let the number of students in two departments be '9n' and '7n', respectively.

      So, 9n - 27 = 7n + 21

      Or, 'n' = 24

      Therefore, number of students in second department = 24 ├Ч 7 = 168
