Question : Simplify. $\cos \left(36^{\circ}-\mathrm{A}\right) \cos \left(36^{\circ}+\mathrm{A}\right)+\cos \left(54^{\circ}-\mathrm{A}\right) \cos \left(54^{\circ}+\mathrm{A}\right)$
Option 1: $\cos A$
Option 2: $\sin 2A$
Option 3: $\cos 2A$
Option 4: $\sin A$
Correct Answer: $\cos 2A$
Solution :
Given: $\cos(36^{\circ}-A) \cos (36^{\circ}+A)+\cos (54^{\circ}-A) \cos (54^{\circ}+A)$ = $\sin[90^{\circ} - (36^{\circ} - A)]\sin[90^{\circ} - (36^{\circ} + A)] + \cos (54^\circ - A) \cos (54^\circ + A)$ = $\sin(54^\circ + A)\sin(54^\circ - A) + \cos (54^\circ - A)\cos (54^\circ + A)$ = $\cos(54^{\circ} + A
Question : Directions: If LOVE is coded as 27, then how is COME coded as?
Option 1: 38
Option 2: 18
Option 3: 28
Option 4: 8
Correct Answer: 18
Solution : Given: LOVE is coded as 27.
Add the place value of the letters of the LOVE and divide it by 2 to get the codes – L→12; O→15; V→22; E→5 (12 + 15 + 22 + 5) ÷ 2 = 27 So, LOVE is coded
Question : What is the value of $1.5-0.5+\{(9+2)-5\}$?
Option 1: 7
Option 2: 11
Option 3: 9
Option 4: 5
Correct Answer: 7
Solution : $1.5-0.5+\{(9+2)-5\}$ $= 1.5 - 0.5 + (11 - 5)$ $= 1.5 - 0.5 + 6$ $= 7$ Hence, the correct answer is 7.
Question : Comprehension: In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank. Climatic disasters are (1)_______ increasingly common due to the effects of climate change. These disasters include extreme weather events such as hurricanes, tornadoes, floods, and droughts. To mitigate the effects of these disasters, it is essential to invest in disaster preparedness and (2)______ The impact of climatic disasters is not limited to the loss of life and property damage. For example, hurricanes can disrupt the oil and gas industry, leading to higher fuel prices and (3)_______ Floods can damage crops and infrastructure, leading to food shortages and disruptions to transportation systems. Rising temperatures can lead to more frequent heat waves, while changes in precipitation patterns can lead to more (4)_______ droughts and floods. Climatic disasters disproportionately affect vulnerable populations. Collaboration among governments, communities, and businesses is crucial for effective disaster preparedness and response. This involves investing in early warning systems, improving infrastructure and emergency services, and planning for post-disaster recovery. By taking a (5)_______ approach to disaster management, we can reduce the impacts of climatic disasters and build more resilient communities. Select the most appropriate option to fill in the blank 2.
Option 1: regeneration
Option 2: response
Option 3: evaluation
Option 4: manifestation
Correct Answer: response
Solution : The second option is the correct choice.
The sentence discusses the need to mitigate the effects of climatic disasters, investing in disaster preparedness, and the specific types of actions required. Response is the most fitting term because it implies taking action to address and manage
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/consonants/vowels in the word.) Anklet : Ankle :: Bracelet : ?

So, the opposite pairs are –
Therefore, the opposite face of A is E. Hence, the fourth option is correct.
Question : A genetically engineered form of brinjal known as the BT brinjal has been developed. The objective of this is
Option 1: to make it pest-resistant
Option 2: to improve its taste and nutritive value
Option 3: to make it drought-resistant
Option 4: to make its shelf life longer
Correct Answer: to make it pest-resistant
Solution : The correct option is to make it pest-resistant.
BT brinjal is a variety of brinjal that has been genetically modified to express a protein derived from the bacteria Bacillus thuringiensis (BT). This protein functions as a natural pesticide, protecting the plant from
