Question

If square of a number ends with $5$, then its cube ends with $25$. State whether statement is True or False.

• A. True
• B. False

Answer 1

The correct option is B False

Consider a contrary example

Let us consider $35$,

$\begin{array}{rcl}& \Rightarrow & {35}^2=1225\\ {35}^3& =& 1225\times 35\\ & \Rightarrow & {35}^3=42875\end{array}$

${35}^3$ does not end with $25$ but its square ends with $5$.

Hence, the statement is False.
