Verbal Reasoning QUESTION #8080

Before Maria changed jobs, her salary was 24 percent more than Julio's salary. After Maria changed jobs, her new salary was 24 percent less than her old salary.

Compare:

Column A: Julio's salary

Column B: Maria's new salary

Column A is greater
Column B is greater✔️
The two quantities are equal
The relationship cannot be determined

Correct Answer Logic:

Let Julio's salary be $J$ and Maria's old salary be $M_{old}$.

Given: $M_{old} = 1.24J$

Maria's new salary: $M_{new} = M_{old} - 0.24M_{old} = 0.76M_{old} = 0.76(1.24J) = 0.9424J$

Comparing:

Column A: $J = 1.0J$
Column B: $0.9424J$

Since $1.0 > 0.9424$, Column A (Julio's salary) is greater than Column B (Maria's new salary).

Therefore, Column A is greater.

Statistics QUESTION #1997

Question 2

Using moments $\mu_1' = -0.35$, $\mu_2' = 2.09$ about $a = 16$, the variance $\mu_2$ (second central moment) of the distribution equals:

2.09
1.9675✔️
2.2125
1.7

Correct Answer Logic:

Variance $\mu_2 = \mu_2' - (\mu_1')^2 = 2.09 - (-0.35)^2 = 2.09 - 0.1225 = 1.9675$. The central moment is obtained by subtracting the squared first raw moment from the second raw moment.

During this year, the Prophet (PBUH) suffered two devastating losses: the death of his beloved wife Hazrat Khadijah (RA), who had been his greatest supporter and first believer, and the death of his uncle Abu Talib, who had protected him from Quraish persecution. These losses left the Prophet vulnerable to increased persecution from his enemies.

Mathematics QUESTION #6962

Question 20

Given $x=\sin^{-1}(\sin 10)$ and $y=\cos^{-1}(\cos 10)$, find $y-x$.

10
$7\pi$
$\pi$✔️

Correct Answer Logic:

Note $10$ radians. Since $3\pi\approx9.42$ and $4\pi\approx12.57$: $3\pi<10<4\pi$.

For $x$: $\sin^{-1}(\sin10)$. Principal range $[-\pi/2,\pi/2]$. $10\approx10-3\pi\approx0.58$, but $10-(3\pi)\approx0.58<\pi/2$? $3\pi\approx9.42$, $10-3\pi\approx0.58$. Since $\sin(10)=\sin(\pi-(10-3\pi))=\sin(4\pi-10)$... more carefully: $10 = 3\pi + (10-3\pi)$, $\sin(10)=\sin(3\pi+(10-3\pi))=-\sin(10-3\pi)$. So $x=\sin^{-1}(-\sin(10-3\pi))=-(10-3\pi)=3\pi-10$.

For $y$: $\cos^{-1}(\cos10)$, range $[0,\pi]$. $10-3\pi\approx0.58\in[0,\pi]$, so $y=10-3\pi$... wait: $\cos(10)=\cos(4\pi-10)$ and $4\pi-10\in[0,\pi]$. So $y=4\pi-10$.

$y-x=(4\pi-10)-(3\pi-10)=\mathbf{\pi}$
