Distribution Analysis | MCQs

Explanation

Given:

Asad : Sania = 2 : 3

Sania : Fahad = 4 : 3

To find the continued ratio, we need to make Sania's ratio equivalent in both. Let's adjust the ratios:

Asad : Sania = 2 : 3 = 8 : 12 (multiplied both parts by 4)

Sania : Fahad = 4 : 3 = 12 : 9 (multiplied both parts by 3)

Now, combining them:

Asad : Sania : Fahad = 8 : 12 : 9

Explanation

Given:

3/4 of the police employees are not graduates.

This means:

1/4 of the police employees are graduates.

To find the ratio of graduates to non-graduate employees:

Graduates : Non-graduates = 1/4 : 3/4

Simplify the ratio:

Graduates : Non-graduates = 1 : 3

Explanation

Initial ratio: Boys:Girls = 8:5

After 22 more girls join:

Boys = 8x, Girls = 5x + 22 (where x is a constant)

Total students = 286 + 22 = 308

8x + 5x + 22 = 308

13x = 286

x = 22

Boys = 8x = 176

Girls = 5x + 22 = 132

New ratio = Boys:Girls = 176:132 = 4:3 (after simplification)

Explanation

The third class in the frequency distribution corresponds to the class limits 15-19, and its frequency is given as 50.

Therefore, the frequency of the third class is 50.
