Question : The abbreviation LHC stands for which machine?
Option 1: Light Heat Collider
Option 2: Large Hadron Collider
Option 3: Long Heavy Collider
Option 4: Large High Collider
Correct Answer: Large Hadron Collider
Solution : The correct answer is the Large Hadron Collider.
The largest and most potent particle accelerator in existence is the Large Hadron Collider (LHC). It is made up of a 27-kilometre-long ring of superconducting magnets with several accelerating structures to increase the particle energy along the way. When discussions about constructing a Large Electron Positron (LEP) collider at CERN first started in 1976, they marked the beginning of the Large Hadron Collider (LHC).

Question : Directions: In a certain code language, DAME is coded as 2976, TIME is coded as 9254, SAPE is coded as 8369, and MOST is coded as 1523. What is the code for ATP in that code language?
Option 1: 851
Option 2: 658
Option 3: 651
Option 4: 869
Correct Answer: 658
Solution : Given: 1. DAME is coded as 2976 2. TIME is coded as 9254 3. SAPE is coded as 8369 4. MOST is coded as 1523
After comparing each letter of the word and numbers, we get – In words 1, 2 and 4, M and 2 are common. In words 1, 2 and 3, E and 9 are common. In words 1 and 3, A and 6 are common. In words 3 and 4, S and 3 are common. In words 2 and 4, T and 5 are common. The remaining words and code in word 1 are D and 7; in word 2 are I and 4; in word 3 are P and 8; in word 4 are O and 1. Finally, M ⇒ 2; E ⇒ 9; A ⇒ 6; S ⇒ 3; T ⇒ 5; D ⇒ 7; I ⇒ 4; P ⇒ 8; O ⇒ 1
So, the code for ATP will be 658. Hence, the second option is correct.
Question : Divide INR 1488 among X, Y, and Z. If the shares are in the ratio X : Y = 4 : 5 and Y : Z = 7 : 6, then find out the share of Z.
Option 1: INR 460
Option 2: INR 450
Option 3: INR 470
Option 4: INR 480
Correct Answer: INR 480
Solution : INR 1488 is divided among X, Y, and Z. ⇒ X + Y + Z = 1488 .......(1) Given, X : Y = 4 : 5 and Y : Z = 7 : 6 ⇒ X = $\frac{4}{5}$Y and Y = $\frac{7}{6}$Z ⇒ X = $\frac{4}{5}\times \frac{7}{6}$Z = $\frac{14}{15}$Z Putting in (1), we get, $\frac{14}{15}$Z + $\frac{7}{6}$Z + Z = 1488 ⇒ $\frac{1}{30}$(28Z + 35Z + 30Z) = 1488 ⇒ 93Z = 44640 ⇒ Z = 480 Hence, the correct answer is INR 480.

Question : Directions: A series is given below with one term missing. Choose the correct alternative from the given ones that will complete the series. DP, EY, FJ, ?
Option 1: GX
Option 2: GS
Option 3: GT
Option 4: GW
Correct Answer: GW
Solution : Given: DP, EY, FJ, ?
Add 1 and 9 to the positional value of the first and second letters respectively of the previous term to obtain the next term in the series – First letter of the series→D + 1 = E; E + 1 = F; F + 1 = G Second letter of the series→P + 9 = Y; Y + 11 = J; J + 13 = W
So, GW is the missing term. Hence, the fourth option is correct.
Question : Directions: Identify the figure given in the options which when put in place of the question mark (?) will logically complete the series.

Question : If $\frac{1}{a}–\frac{1}{b}=\frac{1}{a–b}$, then the value of $a^{3}+b^{3}$ is:
Option 1: 0
Option 2: –1
Option 3: 1
Option 4: 2
Correct Answer: 0
Solution : Given: $\frac{1}{a}–\frac{1}{b}=\frac{1}{a–b}$ ⇒ $\frac{b–a}{ab}=\frac{1}{a–b}$ ⇒ $(b–a)(a–b)=ab$ ⇒ $(a–b)^{2}=–ab$ ⇒ $a^{2}+b^{2}–2ab=–ab$ ⇒ $a^{2}+b^{2}=ab$ ⇒ $a^{2}+b^{2}-ab=0$ We know $a^3+b^3=(a+b)(a^2+b^2-ab)$ So, $a^3+b^3=0$ Hence, the correct answer is $0$.
Question : Neeti wants to use an input device that works by sensing the user's finger movement and downward pressure. Which among the following should she use?
Option 1: Scanner
Option 2: Touchpad
Option 3: Light pen
Option 4: Keyboard
Correct Answer: Touchpad
Solution : The correct answer is Touchpad.
Neeti should use a touchpad. Touchpads are input devices that detect the movement and pressure of a user's finger on a flat surface. They are commonly found on laptops and are used for navigating the cursor on the screen, clicking, and performing various gestures. The touchpad matches the description of an input device that senses both finger movement and downward pressure.
