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.

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 $\frac {5}{1}$.
