Question : Directions: In a certain code language, SLEEP is written as TLEEQ. How will DROWSY be written in that language?
Option 1: ERWOSZ
Option 2: EROWSZ
Option 3: ERWOZS
Option 4: ROWSZQ
Correct Answer: EROWSZ
Solution : Given: SLEEP is coded as TLEEQ.
Add 1 to the place value of the first and last letters of SLEEP and the rest of the letters will remain the same to get the required code. S + 1 = T; L→L; E→E; E→E; P +
Question : If $s-\frac{1}{s-8}=20$, then the value of $(s-8)^3-\frac{1}{(s-8)^3}$ is:
Option 1: 1324
Option 2: 1764
Option 3: 1864
Option 4: 1944
Correct Answer: 1764
Solution : Given: $s-\frac{1}{s-8}=20$ ⇒ $s-8-\frac{1}{s-8}=12$ ⇒ $(s-8-\frac{1}{s-8})^3=12^3$ ⇒ $(s-8)^3-(\frac{1}{s-8})^3-3×(s-8)×\frac{1}{(s-8)}(s-8-\frac{1}{s-8})=1728$ ⇒ $(s-8)^3-(\frac{1}{s-8})^3-3×12=1728$ $\therefore(s-8)^3-(\frac{1}{s-8})^3= 1764$ Hence, the correct answer is 1764.
Question : Comprehension: Read the given passage and answer the questions that follow. Difficult times could create feelings of anxiety, insecurity, and fear. As we navigate through undesirable situations and uncertainties, we find that the negativity surrounding the problems consumes our minds. It is in those times that we have to exert ourselves to change our perspective and adopt a more positive and solution-driven attitude. Wise people have always chosen to leverage adversities as opportunities for growth and progress rather than succumb to negative thought patterns. Saint Kabir described how different people respond when challenged by problems: "Gold, virtuous people, and saints are resilient; you may break them a hundred times and yet they will re-join. In contrast, negative people and clay pots are fragile; once shattered, they are broken forever." The distinguishing feature of the successful is that they have a mindset that enables them to remain positive in the face of adversity and even utilise the negative situation for their benefit. The eagle can teach us a few lessons on this. When the storm starts blowing, it does not cower down before it. It flies to a higher point and waits for the wind to blow over. When the storm sets in, the eagle spreads its wings and uses the draft of the wind to rise higher and higher in the sky. It does not run away from the storm; rather, it uses the storm to its advantage. While the storm rages below, the eagle soars above it. The winning attitude to overcome despair and stress is to realise that adversities have opportunities inherent in them, and opportunities do not come without problems. Hence, difficulties and obstacles have a positive side to them as they make us grow from within. A gem gets polished with friction. The finest steel is produced by putting it on fire. Similarly, the more hardships we face, the stronger we become.

Question : The speeds of a boat along the current and against the current are 10 km/hr and 8 km/hr, respectively. What is the speed (in km/hr) of the current?
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 9
Correct Answer: 1
Solution : Let the speed of the boat be $x$ km/hr. The speed of the current is $y$ km/hr. Speed of boat along the current = Speed of boat + Speed of current $x+y$ = 10 km/hr ----(1) Speed of boat against the current = Speed of
Question : The following table gives information on the number of students (in thousands) placed in five different companies during six different years.
What is the difference between the students placed in all companies in the years 2014 and 2012?
Option 1: 9000
Option 2: 7800
Option 3: 8200
Option 4: 7500
Correct Answer: 8200
Solution : Students placed in all companies in the year 2014 = 19.3 + 13.4 + 13.4 + 11.8 + 7.8 = 65.7 thousands Students placed in all companies in the year 2012 = 12.6 + 9.8 + 10.4 + 14.9 + 9.8 = 57.5 thousands $\therefore$
Question : Directions: In the following question, some parts of the sentence may have some errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select "No error."
I (1) / go to school (2) / by walk. (3) / No error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (3)
Solution : The error lies in the third part of the sentence.
When describing the act of walking, it's more appropriate to use the phrase "by walking" instead of "by walk". The gerund form of the verb "walk" i.e., "walking" should be used.
Therefore, the correct
Question : Directions: Two statements are given, followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: Some movies are dramas. Some dramas are fiction. Conclusions: I. Some movies are fiction. II. All fiction is movies.
Option 1: Only conclusion I follows
Option 2: Only conclusion II follows
Option 3: Neither conclusion I nor II follows
Option 4: Both conclusions I and II follow
Correct Answer: Neither conclusion I nor II follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some movies are fiction – From the given Venn diagram, it is evident that there is no overlapping between the
Question : A can do a piece of work in 8 days which B can destroy in 3 days. A has worked for 6 days, during the last 2 days of which B has been destroying; how many days must A work alone to complete the remaining work?
Option 1: $7\ \text{days}$

Option 3: $7\frac{2}{3}\ \text{days}$
Option 4: $8\ \text{days}$
Correct Answer: $7\frac{1}{3}\ \text{days}$
Solution : Time taken by A alone to do the work = 8 days Part of work done by A alone in a day = $\frac{1}{8}$ Time taken by B alone to destroy the work = 3 days Part of work destroyed by B alone in
