QUESTION 20:
A 30kg bag of fertilizer is labelled 15-20-10. This means that it contains 15% nitrogen, 20% phosphorus, and 10% potassium by weight. How many kilograms of nitrogen, phosphorus, and potassium are in the bag?
First, lets find out how many kilograms each ingredient is.
15% of 30= 4.5 kg
20% of 30= 6 kg
10% of 30= 3 kg
4.5+6+3= 13.5 kg
THERE IS 13.5 kg OF NITROGEN, PHOSPHORUS, AND POTASSIUM IN THE BAG.
