Question : If $p=9, q=\sqrt{17}$, then the value of $(p^2-q^2)^{-\frac{1}{3}}$ is equal to:
Option 1: 4
Option 2: $\frac{1}{4}$
Option 3: 3
Option 4: $\frac{1}{3}$
Correct Answer: $\frac{1}{4}$
Solution : Given: $p=9⇒p^2 = 81$ and $q=\sqrt{17}⇒ q^2= 17$ Putting the values in the equation, we get, $(p^2–q^2)^{–\frac{1}{3}}$ $=(81–17)^{–\frac{1}{3}}$ $=(64)^{–\frac{1}{3}}$ $=(4^3)^{–\frac{1}{3}}$ $=(4)^{–{1}}$ $=\frac{1}{4}$ Hence, the correct answer is $\frac{1}{4}$.
Question : Which mechanism is used by the computer virus 'worm' to duplicate itself?
Option 1: Swap
Option 2: Increment
Option 3: Spawn
Option 4: Swarm
Correct Answer: Spawn
Solution : The correct answer is Spawn.
Spawning is the process by which a program makes a duplicate of itself. The new process may now operate independently of the previous process. Worms use spawning to multiply and spread to other computers. When a worm infects a computer,
Question : Directions: In the following question, you have to identify the correct response from the given premises stated according to the following signs. If – means ×, × means +, + means ÷, and ÷ means –, then what will be the value of 40 × 12 + 3 – 6 ÷ 60 = ?
Option 2: 7
Option 3: 16
Option 4: 44
Correct Answer: 4
Solution : Given: – means ×, × means +, + means ÷, and ÷ means –. 40 × 12 + 3 – 6 ÷ 60 = ?
Replace the signs in the given equation as per the instructions and solve the equation – = 40 + 12
Question : Given: $\theta_1+\theta_2=\frac{\pi}{2}$ and $\sin \theta_1=\frac{1}{2}$, find the value of $\theta_2$.
Option 1: $\frac{\pi}{4}$
Option 2: $\frac{\pi}{2}$
Option 3: $\frac{\pi}{3}$
Option 4: $\pi$
Correct Answer: $\frac{\pi}{3}$
Solution : $\theta_1+\theta_2=\frac{\pi}{2}$ and $\sin \theta_1=\frac{1}{2}=\sin30^\circ⇒\theta_1=\frac{\pi}{6}$. Now, $\theta_1+\theta_2=\frac{\pi}{2}$ ⇒ $\frac{\pi}{6}+\theta_2=\frac{\pi}{2}$ ⇒ $\theta_2=\frac{\pi}{2}-\frac{\pi}{6}$ ⇒ $\theta_2=\frac{\pi}{3}$ Hence, the correct answer is $\frac{\pi}{3}$.
Question : Study the below population data of different states and answer the following question.
If the total population of the given states is 3,15,000. Then, what is the total number of illiterate people in Goa and M.P.?
Option 1: 65,520
Option 2: 81,900
Option 3: 1,20,500
Option 4: 90,870
Correct Answer: 65,520
Solution : Given: The total number of people in all states is 3,15,000. The population of the Goa = $\frac{315000 × 12}{100}$ = 37,800 The population of the M.P. = $\frac{315000 × 20}{100}$ = 63,000 In Goa, Literate : Illiterate = 3 : 2 So, Illiterate people
Question : A and B start moving from places X to Y and Y to X, respectively, at the same time on the same day. After crossing each other, A and B take $5 \frac{4}{9}$ hours and 9 hours, respectively, to reach their respective destinations. If the speed of A is 33 km/hr, then the speed (in km/hr) of B is:
Option 1: 22
Option 2: 2
Option 3: $25 \frac{2}{3}$
Option 4: $24 \frac{1}{3}$
Correct Answer: $25 \frac{2}{3}$
Solution : Speed of A = 33 km/hr After crossing each other, Time taken by A to reach destination = $\frac{49}{9}$ hours Time taken by B to reach destination = 9 hours Let the speed of B be v km/hr. Let both A and B meet
Question : Amit can complete a piece of work in 5 hours, Jeevan and Paul together can complete it in 4 hours, while Amit and Paul together can complete it in 3 hours. Approximately, how many hours will Jeevan alone take to complete the work (rounded off to the nearest integer)?
Option 1: 5 hours
Option 2: 6 hours
Option 3: 9 hours
Option 4: 8 hours
Correct Answer: 9 hours
Solution : Amit can complete a task in 5 hours. Work done by Amit in 1 day = $\frac{1}{5}$ Amit and Paul can together complete it in 3 hours. Work done by Amit and Paul in 1 day = $\frac{1}{3}$ So, work done by Paul in
Question : Directions: Select the option that is related to the fifth term in the same way as the second term is related to the first term and the fourth term is related to the third term. 160 : 4 :: 250 : 5 :: 360 : ?
Option 1: 6
Option 2: 9
Option 3: 4
Option 4: 10
Correct Answer: 6
Solution : Given: 160 : 4 :: 250 : 5 :: 360 : ?
Like, √(160 ÷ 10) = √(16) = 4 √(250 ÷ 10) = √(25) = 5 Similarly, √(360 ÷ 10) = √(36) = 6
So, 6 is the required answer. Hence, the first option
