Correct Answer: Option E
Explanation

- If two solids are similar, the ratio of their volumes is equal to the cube of the ratio of their corresponding sides.

Given: Heights of cylinder  -->     21 : 7 or  3 : 1 = \(\frac{3}{1}\) 

                                = 3 times height enlargement

            Volume / Capacity of larger cylinder = 3\(^3\) \(\times\) 250g 

                                = 27 \(\times\) 250g = 6,750 or 6.75kg
