Method 1

$1$ feet = $12$ inches

So $5$ feet $5$ inches = $65$ inches.

So $65$ inches is the actual height of the candidate.

Height which he wrote on certificate = $65$ + ($25\%$ of $65$) = $65+16.25 = 81.25$ inches.

So $Percentage\ correction$

$=  \frac{Wrong\ height - Actual\ Height}{Actual\ height} * 100 $

$= \frac{81.25 - 65}{65} *100 $

$= \frac{16.25}{65} *100 $

$= 25\% $


Method 2

the original height was $5$ feet $5$ inches

But he increased his height by $25\%$ and wrote in the certificate.

So what will he do to make it correct ?

Decrease the height by $25\%$ which is written in the certificate.

So option 3. $25$ is correct answer.
