This is a problem of decoding a given expression based on a set of defined word-to-operator mappings. We need to substitute the words with their corresponding mathematical operators and then evaluate the resulting expression following the order of operations (BODMAS/PEMDAS).
A) 94 is the correct answer because after substituting the operators and following the BODMAS rule, the calculation yields 94.
The question asks to identify the planet that is orange in colour with white bands. This requires knowledge of the visual characteristics of the planets in our solar system.
C) Jupiter is famously known for its distinctive orange, brown, and white banded appearance, which are atmospheric features (zones and belts) caused by powerful winds and different chemical compositions in its atmosphere.
The question asks to identify the specific bacterium responsible for converting milk into curd. This is a common biological process known as fermentation, widely used in food production.
Correct Option: C) Lactobacillus is the bacterium primarily responsible for converting milk into curd through lactic acid fermentation.
The question asks to identify the Railway Minister who presented the 2016 Rail Budget. This is a factual question related to Indian political history and government portfolios.
Correct Option: A) Suresh Prabhu was the Union Minister for Railways from November 2014 to September 2017. He presented the Rail Budgets during this period, including the 2016 Rail Budget.
The question asks for the full form of "SPM" in the context of the environment. This is a common acronym used in environmental science and pollution studies. Recalling the standard terminology related to air pollution will help identify the correct option.
Correct Option: B) Suspended Particulate Matter. SPM refers to microscopic solid or liquid particles suspended in the Earth's atmosphere. These particles can be natural (e.g., dust, pollen, sea salt) or anthropogenic (e.g., smoke, soot, industrial dust) and are a significant air pollutant, impacting human health and the environment.

To calculate the amount after 2 years when interest is compounded half-yearly, we need to adjust the annual interest rate and the time period. The annual rate is divided by 2, and the number of years is multiplied by 2 to get the number of compounding periods. Then, the compound interest formula can be applied.
The formula for the amount (\(A\)) when compounded \(k\) times a year is:
\[ A = P \left(1 + \frac{R/k}{100}\right)^{T \times k} \]In our case, \(k=2\) (for half-yearly compounding), so the formula becomes:
\[ A = P \left(1 + \frac{r}{100}\right)^{n} \]Substitute the values:
\[ A = 10000 \left(1 + \frac{10}{100}\right)^{4} \] \[ A = 10000 \left(1 + 0.1\right)^{4} \] \[ A = 10000 \left(1.1\right)^{4} \]The amount after 2 years, compounded half-yearly, is Rs. 14,641.
Correct Option: D) 14641
The question asks about a significant administrative decision made by Muhammad Bin Tughlaq, specifically the shifting of his capital from Delhi. This is a well-known event in Indian history, often studied for its impact and consequences.
Correct Option: A) Daulatabad was the city to which Muhammad Bin Tughlaq shifted his capital from Delhi. He renamed the city from Deogir to Daulatabad.
This is a coding-decoding question. We need to identify the pattern or rule used to transform "FHNPKMEG" into "GOLF" and then apply the same rule to "RTSUHJBDJL" to find the corresponding word.
B) STICK is the word formed by applying the identified coding pattern.
This question asks for the population variance given the population standard deviation. The relationship between standard deviation and variance is fundamental in statistics. Variance is the square of the standard deviation.
Identify the given value: The population standard deviation (\(\sigma\)) is 4.5.
\[ \sigma = 4.5 \]Recall the relationship between standard deviation and variance: Variance (\(\sigma^2\)) is the square of the standard deviation (\(\sigma\)).
\[ \text{Variance} = (\text{Standard Deviation})^2 \] \[ \sigma^2 = \sigma \times \sigma \]Calculate the variance by squaring the given standard deviation:
\[ \text{Variance} = (4.5)^2 \] \[ \text{Variance} = 4.5 \times 4.5 \] \[ \text{Variance} = 20.25 \]Thus, the population variance is 20.25.
Correct Option: A) 20.25
