Question

The number of students in two sections A and B having different heights is shown in the table given below:

What is the ratio of the total number of students in section A whose height is less than 1.65 metres to the total number of students in section B whose height is less than 1.65 metres?

Height(in metres)	Section A	Section B
1.55	5	4
1.60	9	8
1.62	11	13
1.65	14	10
1.68	6	7
1.71	7	5
1.75	4	3

• A. 25:26
• B. 1:1
• C. 26:25
• D. 25:25

Answer 1

Answer:

B. 1:1

We need the number of students with height less than 1.65 m.

From the table:

Height (m)	Section A	Section B
1.55	5	4
1.60	9	8
1.62	11	13

Total in Section A (< 1.65 m)

5+9+11=25

Total in Section B (< 1.65 m)

4+8+13=25

Therefore, the required ratio is

25:25 = 1:1.
$\boxed{1:1}$
