12.5% of an amount is 25 grams. find the full amount.

if you multiply 12.5% by 4 you get 50%, and 100 grams. Then if you multiply that by 2 more, you get 10% and 200 grams.

Step-by-step explanation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
