In an examination, 300 students appeared. Out of these students; 28 % got first division, 54 % got second division and the remaining just passed. Assume that no student failed. Find the number of students who just passed.

Hence 54 students just passed

Explanation:

Number of students appeared in the examination=300

Number of students got first division=28% of 300=

100

28

×300=28×3=84 students.

Number of students got second division=54% of 300=

100

54

×300=54×3=162 students.

Given that no student failed

∴Number of students who just passed=Total number of students−(Number of students got first division+Number of students got second division)

∴Number of students who just passed=300−(84+162)

=300−246=54

ANSWER

Number of students appeared in the examination=300

Number of students got first division=28% of 300=10028×300=28×3=84 students.

Number of students got second division=54% of 300=10054×300=54×3=162 students.

Given that no student failed

∴Number of students who just passed=Total number of students−(Number of students got first division+Number of students got second division)

∴Number of students who just passed=300−(84+162)

=300−246=54

Explanation:

In an examination, 300 students appeared. Out of these students; 28% got first division, 54% got second division and the remaining just passed. Assuming that no student failed, find the number of students who just passed.
