Question : Directions: If A denotes +, B denotes ×, C denotes –, and D denotes ÷, then what will be the value of the following expression? 45 A 15 D 15 C 14 B 2 = ?
Option 1: 18
Option 2: 12
Option 3: 14
Option 4: 15
Correct Answer: 18
Solution : Given: 45 A 15 D 15 C 14 B 2 = ?
On interchanging the signs given in the equation, the equation becomes – = 45 + 15 ÷ 15 – 14 × 2 = 45 + 1 – 14 × 2 = 45 +
Question : Silk is obtained from:
Option 1: Mulberry tree
Option 2: Saliva of the silk worm
Option 3: Larvae of silk worm
Option 4: Cocoon of silk worm
Correct Answer: Cocoon of silk worm
Solution : The correct option is - Cocoon of silk worm
The larvae of the mulberry silkworm form cocoons from which silk is produced. An organic protein fiber that can be woven into some types of textiles is silk. Certain insect larvae synthesize fibroin,
Question : If $5 \sin^2 A+3 \cos^2 A=4$, $0<A<90°$, then what is the value of $\tan A$?
Option 1: 0
Option 2: 3
Option 3: 1
Option 4: 2
Correct Answer: 1
Solution : Given: $5\sin^2 A+3\cos^2 A=4$ ⇒ $2\sin^2 A+ 3\sin^2A + 3\cos^2 A=4$ ⇒ $2 \sin^2 A+3=4$...........[Using $ \sin^2 A+ \cos^2 A=1$] ⇒ $\sin^2 A=\frac{1}{2}$ ⇒ $\sin A=\frac{1}{\sqrt{2}}$ ⇒ $A=45°$ So, $\tan A=1$ Hence, the correct answer is 1.
Question : Directions: Three of the following number triads are alike in some manner and one is different. Select the odd number triads. (NOTE: The second and third numbers in the given number triads are formed by performing a certain operation on the first number. The same operation is followed in all the number triads except one. Find that odd number triad.)
Option 1: 4 : 16 : 12
Option 2: 15 : 225 : 210
Option 3: 11 : 121 : 110
Option 4: 7 : 49 : 40
Correct Answer: 7 : 49 : 40
Solution : Let's check the options – First option: 4 : 16 : 12→(4)2 = 16; 16 – 4 = 12 Second option: 15 : 225 : 210→(15)2 = 225; 225 – 15 = 210 Third option: 11 : 121 :

Question : Directions: Select the option that is related to the third word in the same way as the second word is related to the first word. (The words must be considered meaningful English words and must not be related to each other based on the number of letters/number of consonants/vowels in the word.) Rice : Grain :: Lentils : ?
Option 1: Pulses
Option 2: Sprouts
Option 3: Cereal
Option 4: Starch
Correct Answer: Pulses
Solution : Given: Rice : Grains :: Lentils : ?
Like, Rice is a small seed that is cultivated from grain plants. Similarly, Lentil is an edible seed that is cultivated from a legume plant, i.e., a variation of pulses.
Hence, the first option is correct.
Question : Directions: In the following question, a sentence is given with a blank to be filled in with an appropriate word. Four alternatives are suggested for each question. Choose the correct alternative out of the four as your answer.

Question : If $\alpha +\beta =90^{\circ}$, then the expression $\frac{\tan \alpha}{\tan \beta}+\sin^{2}\alpha+\sin^{2}\beta$ is equal to:
Option 1: $\sec^{2}\beta$
Option 2: $\tan^{2}\alpha$
Option 3: $\tan^{2}\beta$
Option 4: $\sec^{2}\alpha$
Correct Answer: $\sec^{2}\alpha$
Solution : Given: $\alpha +\beta =90^{\circ}$ Since $\alpha +\beta =90^{\circ}$ $\alpha = 90^{\circ} - \beta$ $\tan\alpha = \tan (90^{\circ} - \beta) = \cot \beta$ $\sin\alpha = \sin (90^{\circ} - \beta) = \cos\beta$. From the given expression, $\frac{\tan \alpha}{\tan \beta}+\sin^{2}\alpha+\sin^{2}\beta$ $ =\frac{\cot \beta}{\tan \beta} + \cos^{2}\beta + \sin^{2}\beta$
