Question

A beaker has a capacity of $900$ mL. James poured $0.125$ L solution in the beaker, Rita poured $0.388$ L solution in the beaker, and Nick poured three times $0.125$ L in the beaker. Find the volume of the beaker which is still empty.

Answer 1

Volume of solution poured by James $=0.125L$
Volume of solution poured by Rita $=0.388L$
Volume of solution poured by Nick $=3\times 0.125L=0.375L$
Total volume of solution poured by all three in the beaker $=0.125+0.388+0.375$
$=0.888L$


Capacity of the beaker $=900mL$
$=0.900L$
Volume of the beaker that is still empty $=0.900-0.888$
$=0.012L$


So, Option B is the correct answer.
