If a number x is 10% less then another number y and y is 10% more than 125, then the value of $\left(x-\frac{3}{4}\right)$ is

123

The correct answer is Option 4: 123

$y = 125 + (10\% \text{ of } 125)$

$y = 125 + 12.5$

$y = 137.5$

$x = y - (10\% \text{ of } y)$

$x = 137.5 - (10\% \text{ of } 137.5)$

$x = 137.5 - 13.75$

$x = 123.75$

Substitute the value of $x$ into the expression $(x - \frac{3}{4})$.

Value $= 123.75 - 0.75$

Value $= 123$
