Answer:

There is insufficient information to give a complete answer to this question.

Explanation:

Without knowing the cross-sectional area of the measuring cylinder
we can not calculate the volume of the stone and therefore we can not calculate the stone's density.

If the cross-sectional area of the measuring cylinder is #a" cm"^2#
then the volume of the stone would be
#color(white)("XXX") (68-40)" cm" xx a " cm"^3 = 28a " cm"^3#
and its density would be
#color(white)("XXX")(50" grams")/(28a"cm"^3)#

#color(white)("XXX")=25/(14a) " gm/cubic cm"#
