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
Answer & explanation
Correct answer: option 4
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 $= 123$
