Question

State true or false:

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

• A. True
• B. False

Answer 1

The correct option is A True

We know, the units place of the cube of a number will be the same as the cube of the units place of the number.

Here, the units place of the number is $5$ (given).

Then, $5^3=5\times 5\times 5=125$, whose last/units digit is also $5$.

So, if a number ends with $5$, then its cube ends with $5$.

That is, the statement is true.

Hence, option $A$ is correct.
