Question

In an examination,33 1/3 percentage of the examinees passed.If 240 examinees failed,find the total number of the examinees!!​

Answer 1

`SOLUTION:-`

`\rm{passed \: percent = { \displaystyle{33 (1)/(3) \%} = (100)/(3)\% }}`

`{ \displaystyle{ \rm{failed \: percent = \left( 100 - (100)/(3) \right)}\%}}`

`\displaystyle{ (3 * 100 - 100)/(3)\% }`

`\displaystyle{ (200)/(3)\% }`

Let,x be the total number of examinees:-

We have,

`\displaystyle{ (200)/(3)\% \: \rm{of \: x = 240} }`

`\displaystyle{ (200)/(3) * (1)/(100) \rm \: x = 240}`

`\displaystyle{ \rm{x = (240 * 3 * 100)/(200) }}`

`\displaystyle{ \rm{x = 360}}`

Hence,required number of examinees = 360 .
