Question : A shopkeeper is allowed a 20% discount on his Advertised price and makes a profit of 25% on his outlay. What is the advertised price (in Rs.) on which he gains Rs. 6000?
Option 1: 36,000
Option 2: 37,500
Option 3: 39,000
Option 4: 42,500
Correct Answer: 37,500
Solution : Given: A shopkeeper is allowed a 20% discount on his advertised price and makes a profit of 25% on his outlay. Let the cost price be 100 units. Selling price = $100×\frac{125}{100}=125$ units (since profit if 25%) Profit = (125 – 100) = 25 units
Question : If $2x+3y=16$ and $xy=9$, then find the value of $8x^3+27y^3$.
Option 1: 1980
Option 2: 2980
Option 3: 1504
Option 4: 2189
Correct Answer: 1504
Solution : Given: $2x+3y=16$ and $xy=9$ We know that $(a+b)^{3}=a^{3}+b^{3}+3ab(a+b)$ ⇒ $(2x+3y)^{3}=8x^{3}+27y^{3}+18xy(2x+3y)$ Putting the given values, we have, ⇒ $(16)^{3}=8x^{3}+27y^{3}+18×9×(16)$ ⇒ $4096=8x^{3}+27y^{3}+2592$ ⇒ $8x^{3}+27y^{3}=4096–2592$ ⇒ $8x^{3}+27y^{3}=1504$ Hence, the correct answer is 1504.

Question : Directions: In the following question, some parts of the sentence may have some errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select "No error".
He was (1) / very kind enough (2) / to invite me. (3) / No error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)

The phrase "very kind enough" is redundant, as "kind enough" already implies a high level of kindness.
Therefore, the correct sentence is: He was kind enough to invite me.
Question : If $(x+\frac{1}{x})=6$ and $x>1$, find the value of $(x^2–\frac{1}{x^2})$.
Option 1: $18 \sqrt{2}$
Option 2: $30 \sqrt{2}$
Option 3: $24 \sqrt{2}$
Option 4: $12 \sqrt{10}$
Correct Answer: $24 \sqrt{2}$
Solution : Given: $(x+\frac{1}{x})=6$, and $x>1$. We know, $(x–\frac{1}{x})^2=(x+\frac{1}{x})^2–4×x×\frac{1}{x}$ ⇒ $(x–\frac{1}{x})^2=(6)^2–4$ ⇒ $(x–\frac{1}{x})=\sqrt{32}=4\sqrt2$ ⇒ $x^2–\frac{1}{x^2}=(x+\frac{1}{x})(x–\frac{1}{x})$ ⇒ $x^2–\frac{1}{x^2}=(6)(4\sqrt2)=24\sqrt2$ Hence, the correct answer is $24\sqrt2$.
