In an examination, 1/5 of the candidates failed. It is known that 240 candidates passed. How many candidates took the examination
1/5 means 20%
Percentage of passed student is 100-20= 80%
So, total number of students attended the exam = 240*100/80= 300
No. Of students failed is 60 that is 1/5 of 300.
Thank you
(1 - 1/5)x = 240
Solve for x.
80percentage

If 240 candidates passed the examination, and this represents 80% of the total number of candidates, then:
240 = 0.8 * x
Solving for x, we get:
x = 240 / 0.8
x = 300
So, the total number of candidates who took the examination is 300.
To find out how many candidates took the examination, we need to use the information given.
Let's assume the number of candidates who took the examination is x.
It is given that 1/5 of the candidates failed, which means 4/5 of the candidates passed.
We are also given that 240 candidates passed.
So, we can set up the equation:
4/5 * x = 240
To solve for x, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by 5/4 (the reciprocal of 4/5):
(4/5 * x) * (5/4) = 240 * (5/4)
On the left side, the 5/4 cancels out the 4/5, leaving us with just x:
x = 240 * (5/4)
Now, we can solve the equation:
x = 300
Therefore, 300 candidates took the examination.
