Question

20% of the boys,who appeared in an examination,got failed and only 400 boys could pass. Find the total number of examinees.

Answer 1

Answer: total number of examines = 500

Step-by-step explanation:

If the total percentage of boys who appeared for the exam is 100%

20% failed

=> 80% of the boys passed

Given 80% of the boys who passed = 400

Let the total number of students be “x”

$\frac{80}{100} * x = 400$

=> $X = 400 * \frac{100}{80}$

=> x = 500

Therefore the total number of examines = 500
