Question : The marked price of a saree is Rs. 200. After allowing a discount of 20% on the marked price, the shopkeeper makes a profit of Rs.16. Find the gain percentage:

Option 1: $11\frac{1}{9}$%

Option 2: $9\frac{1}{11}$%

Option 3: $11$%

Option 4: $8$%

Team Careers360 24th Jan, 2024

Correct Answer: $11\frac{1}{9}$%


Solution : Selling price = 200 - 200×$\frac{20}{100}$ = Rs. 160
Cost price = Selling price – Profit = 160 – 16 = Rs. 144
Gain % = $\frac{Gain}{\text{Cost price}}×100 = \frac{16}{144}×100=\frac{100}{9}$ = $11\frac{1}{9}$%
Hence, the correct answer is $11\frac{1}{9}$%.

Question : If $a+\frac{1}{a}=\sqrt{3}$, then the value of $a^{18}+a^{12}+a^{6}+1$ is:

Option 1: 0

Option 2: 1

Option 3:  –1

Option 4: 4

Team Careers360 20th Jan, 2024

Correct Answer: 0


Solution : Given: $a^{18}+a^{12}+a^{6}+1$
= $a^{6}(a^{12}+1)+1(a^{12}+1)$
= $(a^{6}+1)(a^{12}+1)$-----------------------------------------------(i)
Now, $a+\frac{1}{a} = \sqrt{3}$
Squaring both sides,
$(a+\frac{1}{a})^2 = (\sqrt{3})^2$
⇒ $(a)^2+(\frac{1}{a})^2+2×a×\frac{1}{a} = 3$
⇒ $(a)^2+(\frac{1}{a})^2 = 3-2 = 1$
Cubing both sides,
$((a)^2+(\frac{1}{a})^2)^3 = 1^3$
⇒ $(a)^6+(\frac{1}{a})^6+3×((a)^2+(\frac{1}{a})^2) = 1^3$
⇒ $(a)^6+(\frac{1}{a})^6 = 1 - 3$
⇒ $\frac{((a)^{12}+1)}{(a)^6} =
