A jeweller claims that he sells ornaments made of pure gold that has the relative density of

19.3.

He sells a necklace weighing

25.250 \mathrm{~g f}

to a person. The clever customer weighs the necklace when immersed in pure water and finds that it weighs

23.075 \mathrm{~g f}

in water. Is the ornament made of pure gold?

View answer and explanation

Correct option: A

Not pure gold

Option A (Not pure gold) is correct because the calculated relative density (11.61) is significantly less than the relative density of pure gold (19.3).
