Question

in an exam 90%of the candidate passed and 80 candidates failed. how many candidates appeared in exam​

Answer 1

Answer:

800 students

Step-by-step explanation:

Given -

In an exam,

90% of candidates passed

80 candidates failed

To find -

How many candidates appeared in exam

Solution -

If 90% passed so 10% would fail (100%-90%)

Let us think the total number of students who appeared as x

so

10% of x failed

=> 10% of x = 80

$= > \frac{10}{100} \times x = 80 \\ = > 10 \times x = 80 \times 100 \\ = > x = \frac{80 \times 100}{10} \\ = > x = \frac{8000}{10} \\ = > x = 800$

Hence 800 students appeared in exam.

hope it helps.
