Question : If $a+\frac{1}{a}=3$, then $a^3+\frac{1}{a^3}$ is:
Option 1: 27
Option 2: 24
Option 3: 18
Option 4: 25
Correct Answer: 18
Solution : Given: $(a + \frac{1}{a}) = 3$ (equation 1) The value of $(a^3 + \frac{1}{a^3})$ by using the identity, $[a^3 + \frac{1}{a^3} = (a + \frac{1}{a})^3 – 3(a + \frac{1}{a})]$. Substitute the value from the equation 1 into the above equation, we get, $a^3 + \frac{1}{a^3}
Question : Study the graph and answer the question
Total production of wheat in states A, B, and E is what percentage less than the total production of rice in states C, D, and E?
Option 1: 12.2
Option 2: 12
Option 3: 10
Option 4: 11.1
Correct Answer: 10
Solution : Total production of wheat in states A, B, and E = 500 + 375 + 475 = 1350 Total production of rice in states C, D, and E = 575 + 400 + 525 = 1500 Difference = 1500 – 1350 = 150 The required

Option 1: VCP
Option 2: UCO
Option 3: VCO
Option 4: OCV
Correct Answer: VCO
Solution : Given: SOC : TND :: UDN : ?
Add and subtract 1 alternately from the place value of the letters of the given term, to obtain the required missing term – Like, SOC : TND→S + 1 = T; O – 1 = N; C
Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 63, 56, 49, 42, 35, 28, ?
Option 1: 14
Option 2: 21
Option 3: 22
Option 4: 35
Correct Answer: 21
Solution : Given: 63, 56, 49, 42, 35, 28, ?
In the above-given series, subtract 7 from the previous number to get the next number. 63 – 7 = 56; 56 – 7 = 49; 49 – 7 = 42; 42 – 7 = 35; 35 –
Question : If $\cos\theta - \sin\theta =0$, then $(\sin^8\theta+\cos^8\theta)$ is:
Option 1: $\frac{1}{8}$
Option 2: $ \frac{1}{4}$
Option 3: $\frac{1}{6}$
Option 4: $\frac{1}{2}$
Correct Answer: $\frac{1}{8}$
Solution : Given: $\cos\theta - \sin\theta =0$ ⇒ $\sin\theta = \cos\theta$ $\sin\theta$'s value is only equal with $\cos\theta$ when $\theta = 45°$ ⇒ $\sin\theta = \cos\theta = \frac{1}{\sqrt2}$ $(\sin^8\theta+\cos^8\theta)$ = $(\sin^845°+\cos^845°)$ = $(\frac{1}{\sqrt2})^8+ (\frac{1}{\sqrt2})^8$ = $\frac{1}{16}+\frac{1}{16}$ = $\frac{2}{16}$ = $\frac{1}{8}$ Hence, the correct answer is $\frac{1}{8}$.
Question : A person sells an article for a loss of 18%. If he increases the selling price by INR 144 and decreases the cost price by 30%, then there is a profit of 20%. What is the original selling price?
