Computer Science Engineering
Hello,
Hope you are doing great.
So, if you are wishing to get enrolled in technology field, then it will be better for you to get enrolled in the CSE branch and choose a specialization in the same such IT or AI or Machine Learning. However if you are interested in the other courses, then you can go for the same.
Hope this helps!!
Question : Directions: In a certain code language, ZEAL is coded as 9476 and LAME is coded as 8694. What is the code for M in the given code language?
Option 1: 4
Option 2: 8
Option 3: 6
Option 4: 9
Correct Answer: 8
Solution : Given: 1. ZEAL ⇒ 9476 2. LAME ⇒ 8694
By comparing the coded words, we find that – In words 1 and 2, the common letters are E, A, and L and the common codes are 9, 4, and 6. The remaining letters and code in word 1 are Z and 7 and in word 2 are M and 8. Finally, Z→7; M→8; E/A/L→9/4/6
So, the code for M is 8 in the code language. Hence, the second option is correct.
Question : Directions: A piece of paper is folded and cut as shown below in the question figures. From the given answer figures, indicate how it will appear when opened.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : When the given folded paper is unfolded, it will look like –
Hence, the first option is correct.
Question : Directions: Three statements are given, followed by four conclusions numbered I, II, III, and IV. 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 desks are trays. Some trays are plates. Some plates are desks. Conclusions: I. All desks are plates. II. All plates are desks. III. Some plates are trays. IV. All trays are desks.
Option 1: Only conclusion III follows
Option 2: Only conclusion IV follows
Option 3: Only conclusion II follows
Option 4: Only conclusion I follows
Correct Answer: Only conclusion III follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion I: All desks are plates – From the above diagram, it is clear that only some parts of the circle that are desks overlap with the circle that is plate. So, only some desks are plates. Therefore, this conclusion does not follow. Conclusion II: All plates are desks – From the above diagram, it is clear that only some parts of the circle that are plates overlap with the circle that is desks. So, only some plates are desks. Therefore, this conclusion does not follow. Conclusion III: Some plates are trays – From the above diagram, it is clear that only some parts of the circle that are plates overlap with the circle that is trays. So, only some plates are trays. Therefore, this conclusion follows. Conclusion IV: All trays are desks – From the above diagram, it is clear that only some parts of the circle that are trays overlap with the circle that is desks. So, only some trays are desks. Therefore, this conclusion does not follow.
So, only conclusion III follows. Hence, the first option is correct.
Question : In which of the following years was the Treaty of Salbai signed?
Option 1: 1817
Option 2: 1769
Option 3: 1800
Option 4: 1782
Correct Answer: 1782
Solution : The correct answer is 1782.
The Treaty of Salbai was signed in the year 1782. This treaty was an important agreement between the British East India Company and the Maratha Empire. It was negotiated after the First Anglo-Maratha War (1775–1782) and played a role in defining the territorial boundaries and diplomatic relations between the two powers during that period.
Question : Directions: Select the missing number from the given responses.
Option 1: 46
Option 2: 69
Option 3: 29
Option 4: 78
Correct Answer: 78
Solution : Given:
In each column, the third number is the difference between the first two numbers. Column 2: 96 – 27 = 69 Column 3: 142 – 29 = 113 Similarly, Column 1: (?) – 21 = 57 ⇒ (?) = 57 + 21 ⇒ (?) = 78
So, 78 is the missing number. Hence, the fourth option is correct.
Question : Realisation A/c is a :
Option 1: Nominal A/c
Option 2: Real A/c
Option 3: Personal A/c
Option 4: Real A/c as well as Personal A/c
Correct Answer: Nominal A/c
Solution : To keep track of the sale of these assets and the payment of liabilities, a nominal account called the Realisation account is established. This account aids in determining the firm's profit or loss as a result of the realisation of assets and liabilities at the time of business closure.
Hence the Correct answer is option 1.
Question : If $\cot 2 {A}=\tan \left({A}-48^{\circ}\right)$, then what is the value of $A$?
Option 1: $36^{\circ}$
Option 2: $46^{\circ}$
Option 3: $42^{\circ}$
Option 4: $40^{\circ}$
Correct Answer: $46^{\circ}$
Solution : $\cot 2 {A}=\tan \left({A}-48^{\circ}\right)$ $⇒\tan(90^{\circ}- 2 {A})=\tan \left({A}-48^{\circ}\right)$ $⇒90^{\circ}- 2 {A}=A-48^{\circ}$ $⇒3 {A}= 138^{\circ}$ $\therefore {A}= 46^{\circ}$ Hence, the correct answer is $46^{\circ}$.
