Question

If a square of a number ends with $5$, then its cube ends with $25$.

• A. True
• B. False
• C. Ambiguous
• D. Data insufficient

Answer 1

The correct option is B False

We know, $5^3=125$,

${15}^3=3375$

and ${25}^3=15625$.

Therefore, clearly, if a square of a number ends with $5$, then its cube may or may not end with $25$.

That is, the given statement is false and option $B$ is correct.
