$\bold{\red {Here\: is\: Your \:Answer. }}$

$\bold{\red {Given :}}$
36 g of Sodium Chloride (NaCl) is dissolved in 100 g of water at 293 K.

$\bold{\red { To \: find : }}$
Concentration at 293 Kelvin.

$\bold{\red {Formula\: Applied : }}$
$Concentration =\frac {mass \:of\: salute}{mass\: of\: solution} \times 100$

$\bold{\red {Solution : }}$
Mass of Solution = Mass of Solute + Mass of Solvent
= 36 g + 100 g
= 136 g

Now, Using Formula
$=>\frac{36}{136} \times 100 \\ => \frac {3600}{136}\\=> 26.47 \%$

Hence, The Concentration is 26.47%

$\bold{\red { Note :}}$
The temperature given here does not matter. It is just given to confuse the students.
