Administration QUESTION #9591

Question 2147

A high-performing employee consistently exceeds targets but receives the same annual increment as average performers. According to expectancy theory, what motivational consequence follows, and what retention risk does this create?

The high-performer will maintain performance because achievement motivation is intrinsic and unaffected by extrinsic equity
The high-performer will reduce effort because the perceived link between high performance and valued reward is broken — the effort-performance-outcome chain in expectancy theory is severed, and the organization faces attrition of its best talent to competitors who reward performance differentially✔️
The high-performer will become a mentor to average performers, raising team standards through social influence
The high-performer will increase effort to demonstrate value and justify a higher increment in the next cycle

Correct Answer Logic:

Expectancy theory (Vroom) holds that motivation requires: effort → performance expectancy (effort leads to performance) AND performance → outcome instrumentality (performance leads to reward). When high performers receive identical rewards to average performers, instrumentality collapses — the employee learns that performance level is irrelevant to reward. This destroys the motivational calculus and drives high-performers (who have strongest market alternatives) to exit.

Verbal Reasoning QUESTION #8103

Question 2148

Compare the two quantities below.

Column A: $(0.82)^2 \cdot (0.82)^3$

Column B: $(0.82)^6$

Column A is greater✔️
Column B is greater
The two quantities are equal
The relationship cannot be determined from the information given

Correct Answer Logic:

Using the rule of exponents: $(0.82)^2 \cdot (0.82)^3 = (0.82)^{2+3} = (0.82)^5$.

Now compare $(0.82)^5$ vs $(0.82)^6$.

Since $0 < 0.82 < 1$, multiplying by $0.82$ makes the number smaller. Therefore $(0.82)^5 > (0.82)^6$.

Column A is greater.

Statement of then-existing mental, emotional, or physical condition (Rule 803(3)).✔️
Former testimony (Rule 804(b)(1)).

Correct Answer Logic:

Rule 803 exceptions (like 803(3)) apply regardless of whether the declarant is available as a witness. Rule 804 exceptions require the declarant to be unavailable.

Accounting & Finance QUESTION #9657

Question 2154

In Departmental Accounts, the Hairdressing department has sales of Rs. 9,000 out of total sales of Rs. 54,000. If Repair Expenses of Rs. 4,800 are to be allocated in the ratio of sales, how much is charged to Hairdressing?

Rs. 800✔️
Rs. 1,600
Rs. 2,400
Rs. 533

Correct Answer Logic:

Hairdressing ratio = 9,000/54,000 = 1/6. Repair expenses = 4,800 × 1/6 = Rs. 800. Sales-based allocation is used for selling and distribution-type expenses where the department's revenue generation drives the expense incurrence.

Chemistry QUESTION #1005

Question 2156

Statement (I): Corrosion is an electrochemical phenomenon in which pure metal acts as an anode and impure metal as a cathode. Statement (II): The rate of corrosion is more in alkaline medium than in acidic medium.

Both Statement I and Statement II are true
Statement I is false but Statement II is true
Statement I is true but Statement II is false✔️
Both Statement I and Statement II are false

Correct Answer Logic:

Statement I is correct — in corrosion, pure metal (more reactive) acts as anode and gets oxidized, while impure metal acts as cathode. Statement II is false — corrosion is faster in acidic medium than alkaline medium because $\text{H}^+$ ions accelerate the oxidation process.

Question 2157

In an Independent Branch reconciliation, which of the following is a reason for the difference between the Head Office Account balance in branch books and the Branch Account balance in HO books?

Different depreciation rates applied
Goods in transit from HO to branch✔️
Different accounting policies
Year-end accruals at the branch

Correct Answer Logic:

The two balances may differ due to: (1) cash in transit, (2) goods in transit, and (3) mistakes committed by either party. Goods dispatched by HO but not yet received at branch create a timing difference, causing a temporary mismatch in both parties' books.

Mathematics QUESTION #6036

Question 2159

Two complex numbers $z_1$ and $z_2$ satisfy $|z_2|=1$ and $\dfrac{z_1-2z_2}{2-z_1\bar{z}_2}$ is unimodular, but $z_2$ is not unimodular. Where does $z_1$ lie?

On a line parallel to the $x$-axis
On a line parallel to the $y$-axis
On a circle of radius 2✔️
On a circle of radius $\sqrt{2}$

Correct Answer Logic:

Let $w = \frac{z_1-2z_2}{2-z_1\bar{z}_2}$, with $|w|=1$.

$|z_1-2z_2|^2 = |2-z_1\bar{z}_2|^2$

$(z_1-2z_2)\overline{(z_1-2z_2)} = (2-z_1\bar{z}_2)\overline{(2-z_1\bar{z}_2)}$

$|z_1|^2 - 2z_1\bar{z}_2 - 2\bar{z}_1z_2 + 4|z_2|^2 = 4 - 2z_1\bar{z}_2 - 2\bar{z}_1z_2 + |z_1|^2|z_2|^2$

$|z_1|^2 + 4|z_2|^2 = 4 + |z_1|^2|z_2|^2$

$|z_1|^2(1-|z_2|^2) = 4(1-|z_2|^2)$

Since $|z_2|\neq1$: $|z_1|^2=4\Rightarrow|z_1|=2$. So $z_1$ lies on a circle of radius 2.

Civil Engineering QUESTION #6622

Question 2160

When checking for 'Web Local Yielding' in a beam, the load is assumed to distribute from the outer surface of the flange at a slope of:

1:01
01:02.5
1:05✔️
2.5:1

Correct Answer Logic:

AISC assumes that a concentrated load applied to a flange spreads out at a 1:2.5 slope (1 horizontal for 2.5 vertical). Therefore, the length of the web resisting yielding at the toe of the fillet is $N + 5k$ (for interior loads).
