Question

Answer

Given Information:
- Total number of registered students = 2000
- 1/25 of the registered students did not appear for the examination
- 11/20 of the students who appeared passed the examination

To Find:
The number of students who passed the examination.

Solution:
Step 1: Calculate the number of students who did not appear for the examination.
1/25 of the registered students did not appear for the examination.
Number of students who did not appear = (1/25) * 2000 = 80

Step 2: Calculate the number of students who appeared for the examination.
Number of students who appeared = Total number of registered students - Number of students who did not appear
= 2000 - 80 = 1920

Step 3: Calculate the number of students who passed the examination.
11/20 of the students who appeared passed the examination.
Number of students who passed = (11/20) * 1920 = 1056

Therefore, the number of students who passed the examination is 1056. Option 'B' is the correct answer.
