Question : In an exam, out of a total number of appeared students 87 percent of students passed, and 3250 students failed. What is the total number of students who appeared in the exam?
Option 1: 22,500
Option 2: 25,000
Option 3: 28,000
Option 4: 26,800
Correct Answer: 25,000
Solution :
Given: In an exam, out of a total number of appeared students 87 percent of students passed, and 3250 students failed.
Let the total number of students be $x$.
The number of students who passed the exam = 87% of $x$ = $0.87x$
The number of students who failed the exam = $x-0.87x$ = $0.13x$
So, $0.13x=3250$
⇒ $x=25000$
Hence, the correct answer is 25,000.
