Mushrooms

Grandfather gathered fresh mushrooms. The fifth was wormwood, and we threw it away. The other dried up. He obtained 720 grams of dried mushrooms. How many kilograms did the grandfather collect, and they lost 75% of their weight by drying the mushrooms?

Correct answer:

x =  3.6 kg

Step-by-step explanation:


(x-x/5)·(1-75/100) = 720 / 1000

200x = 720


x = 720/200 = 3.6

x = 18/5 = 3.6
