Question

If a number $x$ is $10$% less than another number $y$ and $y$ is $10$% more than $125$, then $x$ is equal to

• A. $150$
• B. $143$
• C. $140.55$
• D. $123.75$

Answer 1

Answer: (D)

$123.75$

According to question, we have

$y=125+10\%of125=$ $\frac{110}{100}\times 125=137.5$
$x=137.5-10\%of137.5$ $=\frac{90}{100}\times 137.5=123.75$
