Question : Directions: Select the option that is related to the fourth number in the same way as the first number is related to the second number and the fifth number is related to the sixth number. 432 : 111 :: ? : 320 :: 549 : 228
Option 1: 641
Option 2: 591
Option 3: 761
Option 4: 831
Correct Answer: 641
Solution : Given: 432 : 111 :: ? : 320 :: 549 : 228
Subtract 321 from the first term, to get the second term – Like, 432 : 111→432 – 321 = 111 And, 549 : 228→549 – 321 = 228 Similarly, follow the same pattern
Question : Prabodh has done $\frac{1}{2}$ of a job in 30 days. Sapan completes the rest of the job in 45 days. In how many days can they together do the job?
Option 1: 18 days
Option 2: 48 days
Option 3: 27 days
Option 4: 36 days
Correct Answer: 36 days
Solution : Given: Prabodh has done $\frac{1}{2}$ of a job in $30$ days. So, he alone will finish the whole work in $60$ days. Given, Sapan completes half of the work in $45$ days. So, he will complete the whole work in $90$ days. In
Question : Directions: Select the correct mirror image of the given combination when the mirror is placed at line AB as shown.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection. Here, according to the information provided, the mirror is placed on the right side of the figure (on line AB). So, the left side of the reflected image will appear
Question : The perimeter of two similar triangles GST and FAX are 48 cm and 36 cm, respectively. If FA = 12 cm, then GS is:
Option 1: 18 cm
Option 2: 16 cm
Option 3: 24 cm
Option 4: 12 cm
Correct Answer: 16 cm
Solution :
Since the ratio of the corresponding sides of similar triangles is the same as the ratio of their perimeters. $\therefore \triangle$ GST~$\triangle$ FAX ⇒ $\frac{GS}{FA}=\frac{ST}{AX}=\frac{GT}{FX} = \frac{48}{36}$ ⇒ $\frac{GS}{12}= \frac{48}{36}$ $\therefore GS = 16\ \text{cm}$ Hence, the correct answer is 16 cm.
Question : If $\theta$ is an acute angle and $\cos \theta=\frac{39}{89}$, what is the value of $\sin \theta$ ?
Option 1: $\frac{49}{89}$
Option 2: $\frac{79}{89}$
Option 3: $\frac{80}{89}$
Option 4: $\frac{50}{89}$
Correct Answer: $\frac{80}{89}$
Solution : $\cos \theta=\frac{39}{89}=\frac{\text{Base}}{\text{Hypotenuse}}$ Perpendicular = $\sqrt{89^2-39^2}=\sqrt{(89-39)(89+39)}=\sqrt{50×128}=80$ So, $\sin \theta =\frac{\text{Perpendicular}}{\text{Hypotenuse}}= \frac{80}{89}$ Hence, the correct answer is $\frac{80}{89}$.
Question : Which among the following is not required to be the Vice-President of India as of 2022?

To be a Vice president, a person should have completed 35 years of age. To be eligible for the position of Vice-President, a person must
Question : The diameter of a sphere is 14 cm, then the volume of this sphere is (use $\pi=\frac{22}{7}$ ):
Option 1: $1437 \frac{1}{3} \mathrm{~cm}^3$
Option 2: $1683 \frac{1}{3} \mathrm{~cm}^3$
Option 3: $1521 \frac{2}{3} \mathrm{~cm}^3$
Option 4: $2125 \frac{1}{3} \mathrm{~cm}^3$
Correct Answer: $1437 \frac{1}{3} \mathrm{~cm}^3$
Solution : Diameter of sphere = 14 cm So, the radius, r = $\frac{14}{2}$ = 7 cm Volume of sphere = $\frac{4}{3}×\pi × r^3$ = $\frac{4}{3}×\frac{22}{7} × 7^3$ = $\frac{4312}{3}$ = $1437\frac{1}{3}\ \text{cm}^3$ Hence, the correct answer is $1437\frac{1}{3}\ \text{cm}^3$.
Question : The serious environmental degradation of Maldives is considered to be essentially due to
Option 1: none of the options
Option 2: industrial pollution of water and air
Option 3: high population density
Option 4: constant soil erosion
Correct Answer: high population density
Solution : The correct answer is high population density.
The Maldives' environment is composed of a delicate and intricate network of various ecosystems. Due to the country's small size in terms of population and land area, as well as the virtual isolation of the majority
Question : Directions: In the following question, select the related number from the given alternatives. 4 : 19 :: 7 : ?
Option 1: 28
Option 2: 52
Option 3: 68
Option 4: 49
Correct Answer: 52
Solution : Given: 4 : 19 :: 7 : ?
Here, find the square of the first number and then add 3 to get the second number. Like, 4 : 19→42 = 16; 16 + 3 = 19 Similarly, for 7 : ?→72 = 49;
