Question

A group of students performed an experiment to determine the percentage of water absorbed by raisins.The initial weight of raisins is 5 grams and final weight is 8 grams. The percentage of water absorbed will be (1) 62.5
(2) 160
(3) 60
(4) 20

Answer 1

Answer:

(2) 160 ( one hundred sixty)

Answer 2

Answer is Option (c)

Explanation:

Let the Initial Weight be  $W_1$ = 5 grams

And the Final Weight be $W_2$  = 8 grams

Net Weight = $W_2 - W_1$ = 8 - 5 = 3 grams

Percentage of Water Absorbed = $\frac {W_2 - W_1}{W_1} \times 100$

= $3 \times 20$

= 60

Option (c)
