Question : Find the value of $\frac{\cos^2 15^{\circ}-\sin^2 15^{\circ}}{\cos^2 145^{\circ}+\sin^2 145^{\circ}}$.
Option 1: $\frac{1}{\sqrt{3}}$
Option 2: $\frac{1}{1-\sqrt{3}}$
Option 3: $\frac{\sqrt{3}}{2}$
Option 4: $\frac{2}{\sqrt{3}}$
Correct Answer: $\frac{\sqrt{3}}{2}$
Solution : $\frac{\cos^2 15^{\circ}-\sin^2 15^{\circ}}{\cos^2 145^{\circ}+\sin^2 145^{\circ}}$ = $\frac{\cos^2 15^{\circ}-\sin^2 15^{\circ}}{1}$ = $\cos (2×15)^{\circ}$ (Since $\cos^2A-\sin^2A=\cos2A$) = $\cos 30^{\circ}$ = $\frac{\sqrt 3}2$ Hence, the correct answer is $\frac{\sqrt 3}2$.
Question : Directions: Select the option related to the third term in the same way as the second term is related to the first term. EFH : BJI :: OPQ : ?
Option 1: MRT
Option 2: LUR
Option 3: LTR
Option 4: MRS
Correct Answer: LTR
Solution : Given EFH : BJI :: OPQ : ?
Subtract 3 from the place value of the first letter and add 4 and 1 to the place value of the second and third letters respectively of EFH to obtain the required code – E – 3
Question : If $\cos (A-B)=\frac{\sqrt{3}}{2}$, and $\cos (A+B)=0$, where $A$ and $B$ are positive acute angles and $A \geq B$, then the measures of $A$ and $B$ are:
Option 1: 80° and 10°
Option 2: 60° and 30°
Option 3: 70° and 20°
Option 4: 50° and 40°
Correct Answer: 60° and 30°
Solution : Given, $\cos (A-B)=\frac{\sqrt{3}}{2}$ and $\cos (A+B)=0$ Since $A$ and $B$ are acute positive angles, $\cos (A-B)=\frac{\sqrt{3}}{2}$ ⇒ $(A-B) = \cos^{-1} \frac{\sqrt{3}}{2}$ ⇒ $(A-B) = 30°$ ------------------ (1) $\cos (A+B)=0$ ⇒ $(A+B) = \cos^{-1} 0$ ⇒ $(A+B) = 90°$ --------------------- (2) Solving (1) and
Question : Directions: Which of the following words will come in the fourth position, if arranged according to the English dictionary?
Option 1: Reef
Option 2: Ready
Option 3: Rainbow
Option 4: Rain

Step 1: Compare the first letter of each word. Since all the words start with the same letter R, then move on to the next letter. Step 2: The second letter of the words is either a or e
Question : A sum of Rs. 21850 amounts to Rs. 28623.50 in 5 years at the rate of simple interest. The rate percent is:
Option 1: 7.2% p.a.
Option 2: 4.8% p.a.
Option 3: 6.2% p.a.
Option 4: 6.8% p.a.
Correct Answer: 6.2% p.a.
Solution : Given: Principal = Rs. 21850 Simple interest = Amount – Principal = Rs. 28623.50 – 21850 = 6773.5 Time = 5 years Rate = to find Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ ⇒ $6773.5=\frac{21850 × \text{Rate} × 5}{100}$ ⇒ Rate = $\frac{6773.5\times100}{21850
Question : Directions: In the following question, out of the four alternatives, select the alternative that will improve the bold part of the sentence. In case no improvement is needed, select "No Improvement."

Question : What is the value of $17 ÷ 34 + 2 × 12 ÷ 6 - 5 × 3 ÷ 6$?
Option 1: 2
Option 2: 3
Option 3: 4.5
Option 4: 3.5
Correct Answer: 2
Solution : $17 ÷ 34 + 2 × 12 ÷ 6 - 5 × 3 ÷ 6$ $=\frac{1}{2} + 2 × 2 - 5 × \frac{1}{2}$ $=\frac{1}{2} + 4 - \frac{5}{2}$ $=\frac{9}{2} - \frac{5}{2}$ $=\frac{4}{2}$ $= 2$ Hence, the correct answer is 2.

Question : The average of 5 consecutive integers starting with 'm' is n. What is the average of 6 consecutive integers starting with (m + 2)?
Option 1: $\frac{2n+5}{2}$
Option 2: $(n+2)$
Option 3: $(n+3)$
Option 4: $\frac{2n+9}{2}$
Correct Answer: $\frac{2n+5}{2}$
Solution : Average of 5 consecutive integers starting with 'm' = n Let m, m + 1, m + 2, m + 3, m + 4 be the 5 consecutive integers. Average of 5 consecutive integers = middle term $n$ = m + 2---------------------------------(i) Then 6 consecutive
