Answer:
210 kg.
Step-by-step explanation:
We have to decrease 240 kg by [tex]12\frac{1}{2}[/tex]%.
First we have to find what is [tex]12\frac{1}{2}[/tex]% of 240 kg.
Now, [tex]12\frac{1}{2}[/tex]% is equivalent to [tex]\frac{25}{2} \%[/tex].
So, [tex]\frac{25}{2} \%[/tex] of 240 kg is equal to [tex]\frac{240 \times 25}{2 \times 100} = 30[/tex].
Therefore, decreasing 30 kg from 240 kg will be equal to (240 - 30) kg = 210 kg. (Answer)
