Solution

Step : Evaluating the given expression

Given,
$30 %$ of $200 + 20 %$ of $450 - 25 %$ of $600$
$= (\frac{30}{100} \times 200) + (\frac{20}{100} \times 450) - (\frac{25}{100} \times 600)$
$= (30 \times 2) + (2 \times 45) - (25 \times 6)$
$= 60 + 90 - 150 = 150 - 150 = 0$

Hence,
$30 %$ of $200 + 20 %$ of $450 - 25 %$ of $600 = 0$ .
