Question : A wavelength of 0.3 m is produced in air and it travels at a speed of 300m/s. Then, it will be an:
Option 1: Audible Wave
Option 2: Infrasonic Wave
Option 3: Ultrasonic Wave
Option 4: Microwave
Correct Answer: Audible Wave
Solution : The correct option is the Audible Wave.
The audible range for humans is between 20 Hz and 20,000 Hz. The speed of a wave (v) is related to its wavelength (λ) and frequency (f) by the equation: v=f⋅λ. With a wavelength of 0.3
Question : The bar graph given below shows the foreign trade by two countries A and B in 5 different years.
J1 = The total foreign trade by country A in all 5 years. J2 = The total foreign trade by country B in all 5 years. What is the value of (J2 – J1)?
Option 1: 125
Option 2: 115
Option 3: 95
Option 4: 75
Correct Answer: 115
Solution : From the bar graph, - For country A (J1): 170 + 150 + 75 + 65 + 35 = 495 - For country B (J2): 45 + 105 + 195 + 175 + 90 = 610 So, the value of (J2 – J1) = 610

Question : In a two-digit number, the digit at unit's place is 1 less than twice the digit at the ten's place. If the digit at unit's and ten's place are interchanged, the difference between the new and the original number is less than the original number by 20. The original number is:
Option 1: $59$
Option 2: $23$
Option 3: $35$
Option 4: $47$
Correct Answer: $47$
Solution : Let the tens digit be $x$ so the unit digit is $(2x - 1)$. Original number = $10x + 2x - 1= 12x - 1$. After the interchange, new number = $10(2x - 1) + x = 20x - 10 + x = 21x –10$.
Question : Directions: In the following question, select the related number from the given alternatives. $\frac{1}{4}: \frac{1}{8}:: \frac{2}{3} :\ ?$
Option 1: $\frac{1}{3}$
Option 2: $\frac{1}{2}$
Option 3: 1
Option 4: $\frac{1}{4}$
Correct Answer: $\frac{1}{3}$
Solution : Given: $\frac{1}{4}: \frac{1}{8}:: \frac{2}{3} :\ ?$
Multiply the first number by $\frac{1}{2}$ to obtain the second number of each pair. Like, $\frac{1}{4}: \frac{1}{8}$→$\frac{1}{4}$ × $\frac{1}{2}$ = $\frac{1}{8}$ Similarly, follow the same pattern for $\frac{2}{3} :\ ?$→$\frac{2}{3}$ × $\frac{1}{2}$ = $\frac{1}{3}$
So, $\frac{2}{3}$ is related to
Question : Directions: AKM is related to DNP in a certain way based on the English alphabetical order. In the same way, BTS is related to EWV. To which of the following is LGK related following the same logic?
Option 1: OJN
Option 2: MHC
Option 3: KGL
Option 4: ADH
Correct Answer: OJN
Solution : Given: AKM is related to DNP and BTS is related to EWV.
Add 3 to the place value of letters of AKM, to get the required code – A + 3 = D; K + 3 = N; M + 3 = P Thus, AKM
