A) 2
B) 50
C) 92
D) 96
E) 98
Which method will you apply?
At the start:
1 pound cucumber, 99 pounds water
After the evaporation:
1 pound cucumber = 2% of the total weight
Now look at the answer choices. Only answer choice B works:
.02*50 = 1.
The correct answer is
B.
The equation would look like this:
1 pound cucumber = 2% of the total weight
1 = .02x
x = 1/.02 = 100/2 = 50.
