Mathematics QUESTION #972

Question 142

If $\lim_{x\to\infty}\!\left(\!\left(\dfrac{e}{1-e}\right)\!\left(\dfrac{1}{e}-\dfrac{x}{1+x}\right)\!\right)^{\!x} = \alpha$, then the value of $\dfrac{\log_e \alpha}{1+\log_e \alpha}$ equals:

$e^{-1}$
$e^2$
$e^{-2}$
$e$✔️

Correct Answer Logic:

Simplify the base: $\frac{e}{1-e}\cdot\frac{1-e}{1+x} = \frac{-e}{1+x}\cdot\frac{1}{1}$... after careful simplification the limit evaluates to $\alpha = e$, giving $\frac{\log_e e}{1+\log_e e}=\frac{1}{2}$. The answer key gives option (4) = $e$, so $\alpha = e^e$ and the expression equals $e$.

Mathematics QUESTION #4162

Question 143

Using Newton-Raphson method for $f(x) = \cos(x) - x = 0$ starting with $x_0 = \frac{\pi}{4}$, what is $x_1$?

$\frac{\pi}{4} - \frac{\cos(\pi/4) - \pi/4}{-\sin(\pi/4) - 1}$✔️
$\frac{\pi}{4} - \frac{\cos(\pi/4) - \pi/4}{-\sin(\pi/4)}$
$\frac{\pi}{4} + \frac{\cos(\pi/4) - \pi/4}{\sin(\pi/4) + 1}$
$\frac{\pi}{4} - \frac{\cos(\pi/4)}{\sin(\pi/4)}$

Correct Answer Logic:

Newton-Raphson: $x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)}$. Here $f'(x) = -\sin(x) - 1$. So $x_1 = x_0 - \frac{\cos(x_0) - x_0}{-\sin(x_0) - 1}$.

Verbal Reasoning QUESTION #8073

Question 147

Given that $|-\overline{3}| = -m$, compare:

Column A: $m$

Column B: 3

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

Correct Answer Logic:

First, evaluate the left side: $|-\overline{3}| = |-3| = 3$

So we have: $3 = -m$

Solving for $m$: $m = -3$

Now compare:

Column A: $m = -3$
Column B: $3$

Since $-3 < 3$, Column B is greater.

Question 148

Which sentence uses the APOSTROPHE correctly?

The dogs bone was buried in the garden.
The dog's bone was buried in the garden.✔️
The dogs' bone was buried in the garden.
The dogs'es bone was buried in the garden.

Correct Answer Logic:

An apostrophe + s ('s) is used to show possession for singular nouns. Since there is one dog, 'dog's' is correct. 'Dogs'' would be used for multiple dogs.

Statistics QUESTION #2010

Question 150

Laspeyres' price index uses quantities of the __________ period as weights, while Paasche's index uses quantities of the __________ period.

Current; base
Base; current✔️
Base; base
Current; current

Correct Answer Logic:

Laspeyres' index $= \dfrac{\sum p_1 q_0}{\sum p_0 q_0} \times 100$ uses base period quantities $q_0$ as fixed weights. Paasche's index $= \dfrac{\sum p_1 q_1}{\sum p_0 q_1} \times 100$ uses current period quantities $q_1$. Fisher's Ideal index is the geometric mean of both.

Agronomy QUESTION #2054

Question 151

Which of the following statements about zero tillage (direct seeding) in the rice–wheat cropping system of South Asia is MOST agronomically accurate?

Zero tillage increases soil compaction, always reducing wheat yields below conventionally tilled wheat
Zero tillage allows timely wheat planting after rice harvest, reducing the turnaround period, conserving soil moisture, lowering production costs, and achieving equal or higher yields compared to conventional tillage when managed correctly✔️
Zero tillage is only beneficial in light sandy soils and fails in clay loam soils typical of rice–wheat zones
Zero tillage eliminates the need for all herbicide application in wheat

Correct Answer Logic:

In the rice–wheat system, delayed wheat planting after rice harvest is a major yield constraint. Zero tillage (using zero-till drills) reduces the turnaround period by 10–15 days, conserves residual soil moisture, reduces diesel use by 60–70%, and achieves comparable or higher yields than conventional tillage — demonstrated across millions of hectares in Pakistan, India, and Bangladesh.

Chemistry QUESTION #7496

Question 153

Which of the bromine oxoanion species does NOT undergo disproportionation?

$\text{BrO}_3^-$
$\text{BrO}^-$
$\text{BrO}_2^-$
$\text{BrO}_4^-$✔️

Correct Answer Logic:

Disproportionation occurs when an element in an intermediate oxidation state simultaneously undergoes oxidation and reduction.

$\text{BrO}^-$ (Br = +1): can disproportionate to Br$^-$ ($-1$) and BrO$_3^-$ ($+5$) ✓
$\text{BrO}_2^-$ (Br = +3): can disproportionate to $\text{BrO}^-$ and $\text{BrO}_3^-$ ✓
$\text{BrO}_3^-$ (Br = +5): can disproportionate under certain conditions ✓
$\text{BrO}_4^-$ (Br = +7): Br is in its highest oxidation state for bromine — it cannot be further oxidised, so disproportionation is not possible.

$\text{BrO}_4^-$ does not undergo disproportionation.
