Option 1: 369
Option 2: 504
Option 3: 444
Option 4: 568
Correct Answer: 504
Solution : Add one to the first and second numbers and then multiply the resultants to get the third number – Row I: (11 + 1) × (14 + 1) = 12 × 15 = 180 Row II: (17 + 1) × (18 + 1) = 18
Question : Which chemical law proposes that "soft drinks and soda bottles are sealed under high pressure to increase the solubility of CO2?"
Option 1: Dalton’s Law
Option 2: Henry's Law
Option 3: Ohm's Law
Option 4: Raoult’s Law
Correct Answer: Henry's Law
Solution : The correct answer is Henry's Law.
Henry's Law is one of the gas laws formulated by the British chemist William Henry in 1803.
According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the pressure of the
Question : Which of the following controls the wind speed?
Option 1: Pressure gradient
Option 2: Rotation of Earth
Option 3: Insolation
Option 4: None of the options is correct
Correct Answer: Pressure gradient
Solution : The correct answer is Pressure gradient.
Differences in air pressure can cause air masses to travel from one point to another. Air masses tend to move from high-pressure locations to low-pressure locations. As a result, winds blow from high-pressure zones to low-pressure areas. Hence

Question : A person standing at a distance looks at a building having a height of 1000 metres. The angle between the top of the building and the ground is 30o. At what approximate distance (in metres) is the person standing away from the building?
Option 1: 1000
Option 2: 936
Option 3: 1732
Option 4: 1542
Correct Answer: 1732
Solution : Given: AB = Height of the building = 1000 metres Let the distance of the man from the building, BC be $x$. From $\triangle$ ABC, we get $\tan 30° = \frac{AB}{BC}$ ⇒ $\frac{1}{\sqrt{3}}= \frac{1000}{x}$ ⇒ $ x = 1000\sqrt{3}$ ⇒ $x$ = 1000 × 1.732
Question : Fill in the blank with the most appropriate word.
It is not easy to distinguish a loyal friend ______ a flatterer.
Option 1: from
Option 2: and
Option 3: among

Question : Direction: Given equations are solved on the basis of a certain system. Find the correct answer for the unsolved equation on that basis.
2 + 4 + 6 = 48 and 3 + 2 + 8 = 48 , then 2 + 5 + 7 = ?
Option 1: 48
Option 2: 70
Option 3: 14
Option 4: 59
Correct Answer: 70
Solution : Here, in the given equations, we have–
2 + 4 + 6 = 48 ⇒ 2 x 4 x 6 = 48 3 + 2 + 8 = 48 ⇒ 3 x 2 x 8 = 48
Here, from the above two equations we can
Question : Crocodiles have ______ heart chambers.
Option 1: four
Option 2: five
Option 3: two
Option 4: three
Correct Answer: four
Solution : The correct option is four.
Crocodiles have a four-chambered heart. The heart of a crocodile is similar to that of birds and mammals, exhibiting a complete separation of oxygenated and deoxygenated blood. The four chambers are composed of two atria and two ventricles, allowing
Question : If $2s = a + b + c$, then the value of $s(s - c) + (s - a)(s - b)$ is:
Option 1: $ab$
Option 2: $abc$
Option 3: $0$
Option 4: $\frac{a+b+c}{2}$
Correct Answer: $ab$
Solution : Given: $2s = a + b + c$ ⇒ $s = \frac{a\:+\:b\:+\:c}{2}$ Now, $s(s - c) = (\frac{a\:+\:b\:+\:c}{2})(\frac{a\:+\:b\:+\:c}{2}-c)$ ⇒ $s(s - c) =(\frac{a\:+\:b\:+\:c}{2})(\frac{a\:+\:b\:-\:c}{2})$ Also, $(s - a)(s - b) = (\frac{a\:+\:b\:+\:c}{2}-a)(\frac{a\:+\:b\:+\:c}{2}-b)$ ⇒ $(s - a)(s - b) = (\frac{b\:+\:c\:-\:a}{2})(\frac{a\:+\:c\:-\:b}{2})$ So, $s(s - c) + (s
