Question

In an examination 86% of candidates passed and 70 candidates failed. How many candidates appeared?​

Answer 1

Answer:

let number of candidates be x

no of candidates passed=86/100*x

no.of candidates fail=70.

therefore,86/100*x+70=x

=43/50x+70=x

=70=x-43/50x

=70=7/50x

=70*50/7=x

=x=500

hope it helps

Answer 2

Answer:

kindly see the answer below ...

Step-by-step explanation:

Here, given that

In an examination 86% of candidates passed and 70 candidates failed....

then,

$percntage \: of \: candidates \: failed \: = (100 - 86)\%$

$= 14\%$

therefore,

according to the question...

Let total no. of the candidates be x....

now,

$x \times \frac{14}{100} = 70$

$or \: x = 70 \times \frac{100}{14}$

$or \: x = 500 \: candidates$

afterthat, the total no. of candidates appeared in the examination is 500 candidates..

hope this help u....
