Question

The unit digit in the cube of the number $50$ is:

• A. $1$
• B. $0$
• C. $5$
• D. $4$

Answer 1

Answer: (B)

$0$

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 cube of number $50$ is:

$(50{)}^3=50\times 50\times 50=125000$.

In $125000$, the units digit is $0$.

Therefore, option $B$ is correct.
