Question

In a two digit number, the digit at the units place is $x$ and the digit at tens place is $y$. If $y=5$, then the number is ...............

• A. $50x+5$
• B. $5x$
• C. $30x+5$
• D. $x+50$

Answer 1

Answer: (D)

$x+50$

Let the two digit number be represented by $10y+x$, where $x$ is the digit at one's place and $y$ is at the ${10}^{\prime }s$ place
Given digit at tens place is $y=5$
So, the number formed $=10\left(5\right)+x=50+x$

Hence, option D is correct.
