Question

I don't get this... someone explain this plum thing please...... Before a plum is dried to become a prune, it is 92% water. A pruneis just 20% water. If only water is evaporated in the drying process, how many pounds of prunes can be made with 100 pounds of plums?

Answer 1

21.74 But if it tells you to round I would round to 21 lbs

Explanation:

its basically just a ratio of 92 to 20

92/20=4.6

92-20=72% the amount that is lost

so given that the plum is 100 lbs we know that 72% is depleted

(72/92 = .78)X100= 78 lbs depleted

Lastly 100-78 =22 for the remaining weight of the prunes.
