Question

13. In an examination, there were 2000 candidates. Out of which 75% passed. Find the number of
failed candidates.
​

Answer 1

➤ Answer :-

Number of passed candidates :-

$\longmapsto \sf \:75 \: \% \: of \: 2000$

$\longmapsto \sf \: \frac{75}{100} \times 2000$

$\longmapsto \sf \: \frac{75}{ \cancel{100}} \times \cancel{2000} = 75 \times 20$

$\longmapsto \sf \:1500$

━━━━━━━━━━━━━━━━━━━━━━━━━

Now,

Number of students failed :-

Total students - number of students passed

$\longmapsto \sf \:2000 - 1500$

$\longmapsto \sf \:500$

$\Huge\therefore$500 students failed in the exam.

Answer 2

if 75%passed, then 100 - 75 which is 25% failed

25%=

=25/100x200

=25x2

=50
