Question : Directions: In a certain code language, ABROAD is written as DFORDH, and ACCESS is written as DGECVW. How will AGENCY be written in that language?
Option 1: DKNEFC
Option 2: EKNEFC
Option 3: DJNEFB
Option 4: DKNEGC
Correct Answer: DKNEFC
Solution : Given: ABROAD is written as DFORDH, and ACCESS is written as DGECVW.
Add 3 and 4 in the place value of the first two and last two letters and interchange the position of the third and fourth letter of ABROAD, to get the required code
Question : Directions: In the following question, a sentence is given with a blank that is to be filled in with an appropriate word. Four alternatives are suggested; choose the correct alternative out of them as your answer.
Each time he tried to climb the tree, he failed to do ________.
Option 1: thus
Option 2: then
Option 3: so
Option 4: this
Correct Answer: so
Solution : The third option is the correct answer.
"So" is a conjunctive adverb that is used to refer back to the action mentioned earlier in the sentence, which is "climbing the tree". It connects the failure to the attempted action.
Therefore, the complete sentence is: "Each
Question : If $(4 \sin \theta+5 \cos \theta)=3$, then the value of $(4 \cos \theta-5 \sin \theta)$ is:
Option 1: $3 \sqrt{2}$
Option 2: $4 \sqrt{2}$
Option 3: $2 \sqrt{3}$
Option 4: $2 \sqrt{5}$
Correct Answer: $4 \sqrt{2}$
Solution : $(4 \sin \theta+5 \cos \theta)=3$ Squaring both sides, we get, $⇒16 \sin^2 \theta+25 \cos^2 \theta+40\sin\theta\cos\theta=9$ $⇒16(1-\cos^2 \theta)+25(1-\sin^2 \theta) + 40\sin\theta\cos\theta= 9$ $⇒16-16\cos^2\theta+25-25\sin^2\theta+40\sin\theta\cos\theta=9$ $⇒16\cos^2\theta+25\sin^2\theta-40\sin\theta\cos\theta=16+25-9$ $⇒(4\cos\theta)^2+(5\sin\theta)^2-2\times 5\sin\theta \times 4\cos\theta=32$ $⇒(4\cos\theta - 5\sin\theta)^2 = 32$ $⇒(4\cos\theta - 5\sin\theta) = \sqrt{32}=4\sqrt{2}$ Hence, the correct answer is $4\sqrt{2}$.
Question : If $\cot^2θ = 1 - e^2$, then the value of $\operatorname{cosec} θ + \cot^3θ \sec θ$ is:
Option 1: $\left(2-{e}^2\right)^ \frac{1}{2}$
Option 2: $\left(1-{e}^2\right)^ \frac{3}{2}$
Option 3: $\left(1-{e}^2\right)$
Option 4: $\left(2-{e}^2\right) ^\frac{3}{2}$
Correct Answer: $\left(2-{e}^2\right) ^\frac{3}{2}$
Solution : Given, $\cot^2θ = 1 - e^2$ Consider, $\operatorname{cosec} θ + \cot^3θ \sec θ$ $=\frac{1}{\sinθ} + \frac{\cos^3θ}{\sin^3θ}\frac1{\cosθ}$ $=\frac{\sin^2θ+\cos^2θ}{\sin^3θ}$ $=\frac{1}{\sin^3θ}$ [As $\sin^2θ+\cos^2θ=1$] $=\operatorname{cosec^3}θ$ Also, we know that, $\operatorname{cosec^2}θ=1+\cot^2θ$ ⇒ $\operatorname{cosec^2}θ=1+1-e^2$ ⇒ $\operatorname{cosec^2}θ=2-e^2$ ⇒ $\operatorname{cosec}θ=(2-e^2)^{\frac12}$ ⇒ $\operatorname{cosec^3}θ=(2-e^2)^{\frac32}$ Hence, the correct answer is $(2-e^2)^{\frac32}$.
Question : The table given below shows the number of bikes of 5 different types sold by two companies.
Which of the following statements is correct? I. The Ratio of the number of bikes A sold by C1 to the number of bikes D sold by C2 is 5 : 11. II. The average number of bikes A, B, D and E sold by C1 is 75.
Option 1: Neither I nor II
Option 2: Only I
Option 3: Only II
Option 4: Both I and II
Correct Answer: Only I
Solution : I. Ratio of the number of bikes A sold by C1 to the number of bikes D sold by C2 = 50 : 110 = 5 : 11 II. The average number of bikes A, B, D and E sold by C1 = $\frac{50+30+80+100}{4}$
Question : Directions: A scientist is related to the laboratory in the same way as a teacher is related to ______.
Option 1: School
Option 2: Research
Option 3: Job
Option 4: Students
Correct Answer: School
Solution : Given: A scientist is related to the laboratory.
The first term is a professional and the second term is the workplace – A scientist is a professional and a laboratory is a workplace or environment. Similarly, a teacher is a professional and a school is
Question : If 42 persons consume 144 kg of wheat in 15 days, how many days will 30 persons consume 48 kg of wheat?
Option 1: 8 days
Option 2: 7 days
Option 3: 12 days
Option 4: 6 days
Correct Answer: 7 days
Solution : Given: 42 persons can consume 144 kg of wheat in 15 days. Let in $x$ days 30 persons consume 48 kg of wheat. We know that $\frac{M1D1}{W1}=\frac{M2D2}{W2}$ According to the question, $\frac{42×15}{144}=\frac{30×x}{48}$ ⇒ $x=7$ Hence, the correct answer is 7 days.

Question : Directions: P, Q, R, and S are four friends. P is shorter than Q but taller than R who is shorter than S. Who is the shortest among all?
Option 1: P
Option 2: Q
Option 3: R
