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

The percentage of water absorbed will be = $\frac{\mathrm{Final}\mathrm{weight}-\mathrm{Initial}\mathrm{weight}}{\mathrm{Initial}\mathrm{weight}}\times 100$

$=\frac{8-5}{5}\times 100=60\%$

Hence, the correct answer is option 3.
