Option 2: 96%
Option 3: 98.13%
Option 4: 108.24%
Correct Answer: 104.16%
Solution : Using the given line chart: Total runs scored by Kohli against 5 teams = 1000 + 1100 + 1400 + 500 + 800 = 4800 Total runs scored by Sharma against 5 teams = 800 + 700 + 1000 + 1200 + 1300 = 5000
Question : A retailer wants to sell an item for Rs. 2700 after granting a 10% discount. What is the marked price of the item?
Option 1: Rs. 2850
Option 2: Rs. 3000
Option 3: Rs. 3050
Option 4: Rs. 3110
Correct Answer: Rs. 3000
Solution : The retailer wants to sell the item for Rs. 2700 after a 10% discount. Now, the marked price = selling price × $\frac{100}{100-\text{discount percentage}}$ = 2700 × $\frac{100}{100-10}$ = 2700 × $\frac{100}{90}$ = 3000 Hence, the correct answer is Rs. 3000.

Question : In July 2018, an experiment aboard the International Space Station cooled a cloud of atoms of which chemical element to one ten-millionth of one Kelvin above absolute zero, forming a Bose-Einstein Condensate in space.
Option 1: Rubidium
Option 2: Plutonium
Option 3: Radium
Option 4: Thorium
Correct Answer: Rubidium
Solution : The correct option is Rubidium.
In July 2018, scientists aboard the orbiting lab used the Cold Atom Laboratory to chill a cloud of rubidium atoms to a temperature just one-tenth of a degree above absolute zero, achieving the fifth state of matter known as
Question : The following table shows the number of delivery partners (in thousands) who joined five different companies during six different years.
Find the average number of delivery partners who joined Twiggy in the last 6 years.
Option 1: 2545
Option 2: 2450
Option 3: 2540
Option 4: 2455
Correct Answer: 2450
Solution : Delivery partners who have joined Twiggy In the year 2016 = 1200 In the year 2017 = 1500 In the year 2018 = 2400 In the year 2019 = 2800 In the year 2020 = 3200 In the year 2021 = 3600 Total number of
Question : If an object executes 10 oscillations per second, then its frequency in kilohertz is equal to:
Option 1: 1
Option 2: 10
Option 3: 0.1
Option 4: 0.01
Correct Answer: 0.01
Solution : The correct option is 0.01.
The frequency (f) of an oscillating object is the number of oscillations or cycles it completes per unit of time. The formula to calculate frequency is:
f = number of oscillations/time
In the given scenario, the object executes 10 oscillations
Question : If $\frac{x^{3}+3y^{2}x}{y^{3}+3x^{2}y}=\frac{35}{19}$, what is $\frac{x}{y} =?$
Option 1: $\frac{7}{6}$
Option 2: $\frac{5}{6}$
Option 3: $\frac{5}{1}$
Option 4: $\frac{7}{1}$
Correct Answer: $\frac{5}{1}$
Solution : $\frac{x^{3}+3y^{2}x}{y^{3}+3x^{2}y}=\frac{35}{19}$ Applying componendo and dividendo method, $\frac{x^{3}+3y^{2}x - y^{3}-3x^{2}y}{x^{3}+3y^{2}x + y^{3}+3x^{2}y}=\frac{35-19}{35+19} = \frac{16}{54}$ ⇒ $\frac{(x-y)^3}{(x+y)^3} = \frac{8}{27}$ ⇒ $\frac{x-y}{x+y} = \frac{2}{3}$ ⇒ $\frac{x+y}{x-y}=\frac{3}{2}$ Again, applying the componendo and dividendo method to solve the equation. $\frac{x+y+x-y}{x+y-x+y}=\frac{3+2}{3-2}$ $\Rightarrow\frac{x}{y} = \frac{5}{1}$ Hence, the correct answer is $\frac {5}{1}$.
Question : A rectangular lawn whose length is twice its breadth is extended by having four semi-circular portions on its sides. What is the total area (in ${m}^2$ ) of the lawn if the smaller side of the rectangle is 12 m? (Take $\pi=3.14$ )
Option 1: 853.2
Option 2: 308.64
Option 3: 444
Option 4: 548.32
Correct Answer: 853.2
Solution : Given: Breadth = 12 Length = 2 × Breadth = 2 × 12 = 24 m Area of rectangle = Length × Breadth = 12 × 24 = 288 m2 Area of semi-circle on larger side = $\frac{1}{2}× \pi ×12^2$ = $72\pi\ m^2$ Area
