The Correct Option is D
Solution and Explanation
Let's determine the percentage of candidates who do not get admission.
Let the number of boys be x. Therefore, the number of girls is 2x.
The total number of candidates is x + 2x = 3x.
The number of girls getting admission is 30% of 2x:
\(0.30 \times 2x = 0.6x\)
The number of boys getting admission is 45% of x:
\(0.45 \times x = 0.45x\)
The total number of candidates getting admission is \(0.6x + 0.45x = 1.05x\).
The number of candidates who do not get admission is \(3x - 1.05x = 1.95x\).
The percentage of candidates who do not get admission is:
\(\frac{1.95x}{3x} \times 100\)% = \(65%\)
Thus, the percentage of candidates who do not get admission is 65%.

When the tradwife puts on that georgic, pinstriped dress, she is not just admiring the visual cues of a fantastical past. She takes these dreams of storybook bliss literally, tracing them backward in time until she reaches a logical conclusion that satisfies her. And by doing so, she ends up delivering an unhappy reminder of just how much our lives consist of artifice and playacting. The tradwife outrages people because of her deliberately regressive ideals. And yet her behaviour is, on some level, indistinguishable from the nontradwife’s. The tradwife’s trollish genius is to beat us at our own dress-up game. By insisting that the idyllic cottage daydream should be real, right down to the primitive gender roles, she leaves others feeling hollow, cheated. The hullabaloo and headaches she causes may be the price we pay for taking too many things at face value: our just deserts, served Instagram-perfect by a manicured hand on a gorgeous ceramic dish, with fat, mouthwatering maraschino cherries on top.- CAT - 2024

Different from individuals, states conduct warfare operations using the DIME model— “diplomacy, information, military, and economics.” Most states do everything they can to inflict pain and confusion on their enemies before deploying the military. In fact, attacks on vectors of information are a well-worn tactic of war and usually are the first target when the charge begins. It’s common for telecom data and communications networks to be routinely monitored by governments, which is why the open data policies of the web are so concerning to many advocates of privacy and human rights. With the worldwide adoption of social media, more governments are getting involved in low-grade information warfare through the use of cyber troops. According to a study by the Oxford Internet Institute in 2020, cyber troops are “government or political party actors tasked with manipulating public opinion online.” The Oxford research group was able to identify 81 countries with active cyber troop operations utilizing many different strategies to spread false information, including spending millions on online advertising.- CAT - 2024
