Answer:
The weight one can dry to get 140 grams is 700 grams
Step-by-step explanation:
Fresh grapes looses 80 percent of it weight while drying . To get 140 grams of dried grape we need to know the weight of the fresh grape.
Let the fresh grape weight = y grams
80% of the fresh grape weight will be = 80/100 × y grams
The weight of fresh grape you should dry to get 140 grams = Fresh grape weight - 80% of the fresh grape weight
140 = y - 80/100 × y
140 = y - 0.8 y
140 = 0.2y
divide both sides by 0.2
y = 140/0.2
y = 700 grams
