Answer:
30%
Step-by-step explanation:
Given that,
Initial grains of rice = 250
The final amount of grains of rice = 175
We need to find the percentage decrease in the amount of grains. The percentage decrease in the value is given by :
[tex]\%=\dfrac{250-175}{250}\times 100\\\\=30\%[/tex]
So, the percentage decrease is 30%.
