Option 1: The publishers will release a new book on games next week.
Option 2: The publishers will publish a new book on games next week.
Option 3: The publishers will be releasing a new book next week.
Option 4: The publishers would release a new book next week.
Correct Answer: The publishers will release a new book on games next week.
Solution : The correct choice is the first option.
Explanation:
In the passive voice, the focus is on the receiver of the action rather than the doer. To convert it into an active voice, we need to
Question : Directions: Arrange the following words as per their order in the dictionary. 1. Organ 2. Origin 3. Orient 4. Organic 5. Organise
Option 1: 1, 5, 3, 4, 2
Option 2: 1, 5, 4, 2, 3
Option 3: 1, 4, 5, 3, 2
Option 4: 1, 4, 5, 2, 3
Correct Answer: 1, 4, 5, 3, 2
Solution : Given: 1. Organ 2. Origin 3. Orient 4. Organic 5. Organise
Step 1: Since all the words start with the same letter O, so move on to the next letter. Step 2: The second letter of each word is the
Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 27, ?, 101, 138, 175, 212, 249
Option 1: 64
Option 2: 59
Option 3: 66
Option 4: 72
Correct Answer: 64
Solution : Given: 27, ?, 101, 138, 175, 212, 249
Add 37 to each term to get the next term in the series – 27 + 37 = 64; 64 + 37 = 101; 101 + 37 = 138; 138 + 37 = 175; 175 + 37
Question : Directions: In the following question, some parts of the sentence may have 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."
At his return (1) / we asked him (2) / many questions. (3) / No Error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (1)
Solution : The error lies in the first part of the sentence.
It is not correct because, while describing an action that occurred immediately after someone's return, we often use the preposition "on" or the conjunction "when" to indicate the timing.
So, the correct sentence should be:
Question : If $\operatorname{cosec} \theta + \operatorname{cot} \theta = m$, find the value of$\frac{m^2 – 1}{m^2 + 1}$
Option 1: $1$
Option 2: $0$
Option 3: $\operatorname{cos} \theta$
Option 4: $\operatorname{–sin} \theta$
Correct Answer: $\operatorname{cos} \theta$
Solution : Given: $\operatorname{cosec} \theta + \cot \theta = m$ ........(i) Solution: $\operatorname{cosec}^{2}\theta-\cot^{2}\theta = 1$ (Trigonometric identity) $⇒(\operatorname{cosec} \theta - \cot \theta)(\operatorname{cosec} \theta + \cot \theta) =1$ $⇒(\operatorname{cosec} \theta - \cot \theta)=\frac{1}{m}$ ...........(ii) Adding (i) and (ii), we get, $\operatorname{cosec} \theta + \cot \theta + \operatorname{cosec}
Question : Directions: Select the related letter cluster from the given alternatives. LNPR : TVXZ :: ? : NPRT
Option 1: FHJL
Option 2: FLJH
Option 3: HFLJ
Option 4: JLHF
Correct Answer: FHJL
Solution : Given: LNPR : TVXZ :: ? : NPRT
Here, subtract 8 from the place value of each letter of TVXZ to obtain the required code – T – 8 = L; V – 8 = N; X – 8 = P; Z – 8 =
Question : If $(a+\frac{1}{a})^2=3$, the value of $(a^3+\frac{1}{a^3})$ is:
Option 1: $0$
Option 2: $3(a+\frac{1}{a})$
Option 3: $3(a^2+\frac{1}{a^2})$
Option 4: $1$
Correct Answer: $0$
Solution : Given: $(a+\frac{1}{a})^2=3$ The algebraic identity used is $(a+\frac{1}{a})^3=a^3+\frac{1}{a}^3+3(a+\frac{1}{a})$. $(a+\frac{1}{a})^2=3$ (equation 1) Take the square root of the given equation, we get, $(a+\frac{1}{a})=\sqrt{3}$ (equation 2) Multiplying equation 1 and equation 2, we get, $(a+\frac{1}{a})^2(a+\frac{1}{a})=3\sqrt{3}$ ⇒$(a+\frac{1}{a})^3=3\sqrt{3}$ ⇒ $a^3+\frac{1}{a^3}+3(a+\frac{1}{a})=3\sqrt{3}$ ⇒ $a^3+\frac{1}{a^3}+3\sqrt{3}=3\sqrt{3}$ ⇒ $a^3+\frac{1}{a^3}=3\sqrt{3}–3\sqrt{3}$ ⇒ $a^3+\frac{1}{a^3}=0$ Hence, the correct
Question : Select the correct indirect form of the given sentence.
