Read the following information carefully and answer the question given below:
‘M @ N’ means ‘M is the daughter of N’;
‘M $ N’ means ‘M is the husband of N’;
‘M # N’ means ‘M is the brother of N’;
If R @ S $ T, then which of the following is true?
T is the sister of R
T is the mother-in-law of R
T is the sister-in-law of R
T is the mother of R
This is a blood relation problem where symbols represent relationships. We need to decode the given expression "R @ S \( T" step-by-step to determine the relationship between R and T.
From step 1, R is the daughter of S.
From step 2, S is the husband of T. This means T is the wife of S.
If R is the daughter of S, and S is married to T, then T must be the mother of R.
Correct Option: D) T is the mother of R
Based on our step-by-step decoding, R is the daughter of S, and S is the husband of T. This makes T the wife of S. Therefore, T is the mother of R.
Consider the statements and the following assumptions and decide which of the assumptions is/are implicit in the statement.
Statement:
While playing a card game, a man exclaims to his friend, “What are my chances of winning at least one game against you today?” Assumptions:
I. The friend is an expert player
II. He hasn’t won a game against his friend today
Only I is implicit
Only II is implicit
Neither I nor II is implicit
Both I and II are implicit
This question asks us to identify implicit assumptions in a given statement. We need to analyze the statement carefully and determine what must be true for the statement to make sense or be uttered in that context.
Correct Option: D) Both I and II are implicit
Find the next term in the series:
LR, OQ, SO, _______?
The problem presents a series of two-letter terms. We need to identify the pattern in both the first and second letters of each term to predict the next term in the sequence.
The first letters are L, O, S.
The pattern for the first letters is an increasing increment: +3, +4. Therefore, the next increment should be +5.
So, the first letter of the next term is X.
The second letters are R, Q, O.
The pattern for the second letters is a decreasing decrement: -1, -2. Therefore, the next decrement should be -3.
So, the second letter of the next term is L.
The first letter is X and the second letter is L. Therefore, the next term in the series is XL.
B) XL is the correct option because it follows the established patterns for both the first and second letters of the terms.
The question asks to identify the city near which the Ellora Caves, a significant rock-cut architecture site, are located. This is a factual question related to Indian history and geography, specifically ancient architecture.
A) Aurangabad — Ellora Caves are located approximately 30 kilometers from the city of Aurangabad in Maharashtra. This makes Aurangabad the correct answer.
Choose the INCORRECT one for aldehydes.
C3H7COH → butanal → butyraldehyde
CH3COH → ethanal → acetaldehyde
C2H5COH → propanal → propionaldehyde
CH2COH → methanol → formaldehyde
This question tests knowledge of the nomenclature of aldehydes, specifically their common and IUPAC names. Aldehydes are organic compounds containing a formyl group (\(-\text{CHO}\)). The general formula for an aldehyde can be written as \(\text{R-CHO}\). The IUPAC name for an aldehyde is derived by replacing the -e from the corresponding alkane name with -al. Common names often use prefixes like form-, acet-, propion-, butyr- based on the number of carbon atoms.
D) \(\text{CH}_2\text{COH} \rightarrow \text{methanol} \rightarrow \text{formaldehyde}\)
The question asks to identify the NBA basketball star who won an Oscar for an animation film titled 'Dear Basketball'. This requires knowledge of prominent NBA players and their achievements outside of basketball, specifically in the entertainment industry.
Correct Option: D) Kobe Bryant won an Oscar for Best Animated Short Film in 2018 for 'Dear Basketball'. The film is based on a poem he wrote announcing his retirement from basketball.
The question asks to identify the country that officially recognizes football as its national game. This requires knowledge of the national sports of various countries.
Correct Option: D) Germany has football as its officially recognized national game.
The question asks to identify what BTU (British Thermal Unit) measures. We need to recall the definition and common applications of BTU in physics and engineering.
Therefore, BTU is a measurement of heat content.
D) Heat content — BTU (British Thermal Unit) is a unit of energy that specifically measures heat. It quantifies the amount of heat required to raise the temperature of a specific mass of water by a certain degree.
The question asks to identify an example of Newlands' Octaves. Newlands' Law of Octaves states that when elements are arranged in increasing order of their atomic masses, the properties of every eighth element are similar to those of the first, much like the octaves in music. To answer this, we need to recall the arrangement of elements according to Newlands' Octaves and check which pair fits this pattern.
B) Lithium and Sodium are an example of Newlands' Octaves because Sodium is the eighth element when arranged after Lithium, and they exhibit similar chemical properties as both are alkali metals.
To solve this problem, we need to determine the total vertical distance the elevator must travel. This includes the distance from its starting point above ground to the ground level, and then the distance from the ground level to the specified depth below ground. Once the total distance is found, we can calculate the time taken using the given descent rate.
C) 62 Minutes is the correct answer because the total distance the elevator needs to travel is 465 m (35 m above ground + 430 m below ground), and at a rate of 7.5 m/minute, it will take 62 minutes.
