Professional QUESTION #1843

Under Section 22(2), where no provision for appeal or review exists under the rules, a civil servant aggrieved by any order may make a representation to the authority next above the authority which made the order. However, no representation shall lie on matters relating to what?

Determination of pay or allowances
Determination of fitness to hold a particular post or to be promoted to a higher post or grade✔️

Transfer orders issued by the appointing authority

Correct Answer Logic:

The proviso to Section 22(2) explicitly bars representations on matters relating to the determination of fitness of a person to hold a particular post or to be promoted to a higher post or grade. Fitness determinations are matters of discretion reserved for the competent authority and are not subject to representational challenge.

Statistics QUESTION #1975

Question 7

The first three central moments of a distribution are $\mu_1' = 1$, $\mu_2' = 16$, and $\mu_3' = -40$, all computed about the value $a = 2$. The third central moment $\mu_3$ about the mean equals:

$-86$✔️
$-40$
$76$
$-96$

Correct Answer Logic:

Using the relation $\mu_3 = \mu_3' - 3\mu_2'\mu_1' + 2(\mu_1')^3$: Mean $= a + \mu_1' = 2+1 = 3$, so $d = \mu_1' = 1$. Then $\mu_3 = -40 - 3(16)(1) + 2(1)^3 = -40 - 48 + 2 = -86$. The third central moment is $-86$.

Mathematics QUESTION #1324

Question 14

In the variation of parameters method, the Wronskian of two solutions $y_1$ and $y_2$ is defined as:

$W=y_1y_2'+y_2y_1'$
$W=y_1y_2'-y_2y_1'$✔️
$W=y_1'-y_2'$
$W=y_1y_2$

Correct Answer Logic:

The Wronskian of two functions $y_1$ and $y_2$ is the determinant of the matrix of the functions and their derivatives: $W=\begin{vmatrix}y_1&y_2\\y_1'&y_2'\end{vmatrix}=y_1y_2'-y_2y_1'$. If $W\neq0$ on an interval, $y_1$ and $y_2$ are linearly independent.

Question 19

For an open kinematic chain with $n$ links forming a vector loop from point A to point B, the closure equation in scalar form (x-projection) is:

$\sum_{k=1}^{n} r_k\sin\phi_k = y_B - y_A$
$\sum_{k=1}^{n} r_k\cos\phi_k = x_B - x_A$✔️
$\prod_{k=1}^{n} r_k\cos\phi_k = x_B - x_A$
$\sum_{k=1}^{n} r_k = |r_B - r_A|$

Correct Answer Logic:

The vector loop equation projected onto the x-axis yields $\sum_{k=1}^n r_k\cos\phi_k = x_B - x_A$ and onto y gives $\sum_{k=1}^n r_k\sin\phi_k = y_B - y_A$.
