To find : Solve the expression ?

Solution :

Let the missing value be 'x'.

$x\%\text{ of }450 + 20\% \text{ of }335 = 251$

$\frac{x}{100}\times 450 + \frac{20}{100}\times 335 = 251$

$\frac{450x+6700}{100}= 251$

$450x+6700= 25100$

$450x= 25100-6700$

$450x= 18400$

$x=\frac{18400}{450}$

$x=40.8$

Therefore, the missing value is approx 40.
