Question : An object travels 20 m in 5 seconds and then another 25 m in 10 seconds. What is the average speed?
Option 1: 4 m/s
Option 2: 2 m/s
Option 3: 3 m/s
Option 4: 5 m/s
Correct Answer: 3 m/s
Solution : The total distance traveled = 20 m + 25 m = 45 m The total time taken = 5 s + 10 s = 15 s $\therefore$ The average speed $ = \frac{\text{Total Distance}}{\text{Total Time}} = \frac{45 \, \text{m}}{15 \, \text{s}} = 3 \,
Question : Directions: Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group?
Option 1: 16 – 256
Option 2: 14 – 196
Option 3: 17 – 289
Option 4: 19 – 371
Correct Answer: 19 – 371
Solution : Let's check the options – First option: 16 – 256; 162 = 256 Second option: 14 – 196;142 = 196 Third option: 17 – 289;172 = 289 Fourth option: 19 – 371;192 = 361
Question : If the side of an equilateral triangle is 16 cm, then what is its area?
Option 1: $81 \sqrt{3} \mathrm{~cm}^2$
Option 2: $48 \sqrt{3} \mathrm{~cm}^2$
Option 3: $32 \sqrt{3} \mathrm{~cm}^2$
Option 4: $64 \sqrt{3} \mathrm{~cm}^2$
Correct Answer: $64 \sqrt{3} \mathrm{~cm}^2$
Solution : Given: Sides of the triangle = 16 cm Area of an equilateral triangle with sides $a$ = $\frac{\sqrt3}{4} (a)^2$ $=\frac{\sqrt3}{4}\times 16\times 16$ $= 64\sqrt{3}$ Hence, the correct answer is $64\sqrt3\ \mathrm{cm^2}$.
Question : What is needed to create demand?
Option 1: Production
Option 2: Price
Option 3: Income
Option 4: Import
Correct Answer: Production

Explanation:
Question : Alcohol is more volatile than water because ________ is lower than water.
Option 1: its boiling point
Option 2: its density
Option 3: its viscosity
Option 4: its surface tension
Correct Answer: its boiling point
Solution : The correct answer is its boiling point.
Because of its low boiling point of 78°C, distilling alcohol yields a much stronger solution than wine or beer. Because they are less polar than water, drinking alcohol (ethanol), and many other simple alcohols are more
Question : Two rifles are fired from the same place at a difference of 11 minutes 45 seconds. But a man who is coming towards the same place on a train hears the second sound after 11 minutes. Find the speed of the train (Assuming the speed of sound = 330 m/s).
Option 1: 72 km/h
Option 2: 36 km/h
Option 3: 81 km/h
Option 4: 108 km/h
Correct Answer: 81 km/h
Solution : Given: Time interval between two rifle fires = 11 minutes 45 seconds = 705 seconds Time taken for the man to hear the second sound = 11 minutes = 660 seconds Formula used: Distance travelled by the man on a train in 11 minutes
Question : Which one of the following is the second-highest peak in the world?
Option 1: Dhaulagiri

Correct Answer: K2
Solution : The correct option is K2.
The second-highest peak in the world is K2, also known as Mount Godwin Austen. It is located on the China-Pakistan border in the Karakoram Range of the Himalayas. K2 stands at an elevation of 8,611 meters above sea level.
Question : An angle is greater than its complementary angle by 30°. Find the measure of the angle.
Option 1: 30°
Option 2: 90°
Option 3: 60°
Option 4: 120°
Correct Answer: 60°
Solution : Let $x$ be the angle and the complement of the angle be $(90°-x)$. According to the question, $(90°-x)+30°=x$ ⇒ $2x=120°$ $\therefore x =60°$ Hence, the correct angle is 60°.
