Question : The mean proportional of $a$ and $b$ is $c$. What is the mean proportion of $a^2c$ and $b^2c$?
Option 1: $c$
Option 2: 3$c$
Option 3: $c^3$
Option 4: $c^2$
Correct Answer: $c^3$
Solution : $c^2 = ab$ where c is the mean proportion of a and b Now, the mean proportion of $a^2c$ and $b^2c$ = $\sqrt{b^2c \times a^2c}$ = $a.b.c$ = $c^2 \times c$ = $c^3$ Hence, the correct answer is $c^3$.

Question : The sum of the cubes of two given numbers is 10234, while the sum of the two given numbers is 34. What is the positive difference between the cubes of the two given numbers?
Option 1: 3484
Option 2: 3488
Option 3: 3356
Option 4: 8602
Correct Answer: 3484
Solution : $(a + b)^3= a^3+ b^3+ 3ab(a + b)$ $⇒(34)^3=10234+3ab(34)$ $⇒39304−10234 = 3ab(34)$ $⇒29070 = 102\times ab$ $⇒ab = \frac{29070}{102} = 285$ We know, $(a - b)^2= (a + b)^2 - 4ab$ $⇒(a - b)^2= 34^2 - 4 \times (285)$ $⇒(a - b)^2= 1156 -1140 =
Question : Directions: Select the option figure in which the given figure is embedded. (rotation is NOT allowed)

Question : Comprehension: Read the given passage and answer the questions that follow. Climate policy must now put health at the centre and promote climate change mitigation policies that bring health benefits simultaneously. Health-focused climate policy would help bring about a planet that has cleaner air, more abundant and safer freshwater and food, more effective and fairer health and social protection systems, and, as a result, healthier people. Investments in clean energy will yield health gains that repay those investments twice over. There are proven interventions able to reduce emissions of short-lived climate pollutants, for instance, applying higher standards for vehicle emissions, which have been calculated to save approximately 2.4 million lives per year, through improved air quality and reduce global warming by about 0.5°C by 2050. The cost of renewable sources of energy has decreased significantly in the last few years, and solar energy is now cheaper than coal or gas in most major economies. Question: What is the ANTONYM for the word ‘intervention’, from the passage?
Option 1: Specific
Option 2: Evidence
Option 3: Non-involvement
Option 4: Data
Correct Answer: Non-involvement
Solution : The correct answer is the third option.
Explanation: In the passage, the term intervention is used to refer to actions or measures taken to reduce emissions of short-lived climate pollutants. An antonym in this context would be a term that signifies not taking action

Question : The area of a regular hexagon with side '$a$' is:
Option 1: $\frac{3\sqrt3}{4}a^2$ sq. unit
Option 2: $\frac{12}{2\sqrt3}a^2$ sq. unit
Option 3: $\frac{9}{2\sqrt3}a^2$ sq. unit
Option 4: $\frac{6}{2\sqrt3}a^2$ sq. unit
Correct Answer: $\frac{9}{2\sqrt3}a^2$ sq. unit
Solution : If we break a regular hexagon with side '$a$', then we will get 6 equilateral triangles with sides '$a$'. So, the area of a regular hexagon = 6 × (Area of an equilateral triangle) We know that, the area of an equilateral triangle
Question : If A's salary is 60% more than B's salary, then by what percentage is B's salary less than that of A?
Option 1: 45%
Option 2: 37.5%
Option 3: 47.7%
Option 4: 33.3%
Correct Answer: 37.5%
Solution : A = B + 60% of B A = 160% of B A : B = 160 : 100 = 8 : 5 The required percentage = $\frac{\text{A's salary – B's salary}}{ \text{A's salary}}\times 100$ = $\frac{8-5}{8} \times 100 $ = 37.5% Hence, the correct
