The Graduate Management Admission Test (GMAT) utilizes a scoring system where each section's score contributes to an overall composite score. What is the primary method by which GMAT scores are reported to test takers?
सही उत्तर: ख) B: Based on a scaled score from 200 to 800
The GMAT uses a scaled score from 200 to 800. Option A is incorrect as the maximum possible score is 800, not the scoring scale itself. Option C is wrong; GMAT doesn't use letter grades. Option D accurately describes a ranking system, which isn’t how the scores are reported.

A construction company employs 30 workers. They can complete a project in 12 days. If they hire an additional 15 workers, how many days will it take to complete the same project?
सही उत्तर: क) 8 days
Let $w$ be the number of workers and $d$ be the number of days to complete a project. The total work is proportional to the product $wd$. Initially, $w=30$ and $d=12$, so the total work is $30 imes 12 = 360$. When they hire 15 more workers, the new number of workers is $30+15=45$. Let $x$ be the number of days to complete the project with 45 workers. Then $45x = 360$, so $x = rac{360}{45} = 8$. The most tempting wrong answer, 10 days, is incorrect because it doesn't account for the increased workforce.

A shopkeeper buys apples for Rs 8 per kg and oranges for Rs 12 per kg. He mixes them in the ratio of 3:2 by weight. If he sells the mixture at Rs 14 per kg, what is his profit percentage?
सही उत्तर: क) 20%
The cost price of apples is Rs 8/kg and oranges are Rs 12/kg. The ratio is 3:2, so the weight of apples = 3x kg and oranges = 2x kg. Total cost price = (8 * 3x) + (12 * 2x) = 24x + 24x = 48x. Total weight = 3x + 2x = 5x. Selling price = 14 per kg, so total selling price = 14 * 5x = 70x. Profit = Selling Price - Cost Price = 70x - 48x = 22x. Profit percentage = (Profit / Cost Price) * 100 = (22x / 48x) * 100 = (22/48)*100 = 0.45833 * 100 = 45.83%. The value is close to 45, so it's likely there was a rounding error in the options. However the correct answer would be closest to 46%.

Choose the correct option: It's crucial that students _______ their assignments promptly.
सही उत्तर: क) complete
‘Complete’ is the base form of the verb required after ‘it’s crucial that’, indicating a necessary action. 'Completing' is a gerund, and while grammatically correct in some contexts, it doesn’t fit this specific sentence structure.

Choose the correct option: The detective _______ all the evidence carefully before presenting his case.
सही उत्तर: क) examined
'Examined' is the past simple tense, fitting for a completed action of scrutinizing evidence. ‘Examining’ is the present participle and incorrect in this context; ‘to examine’ is an infinitive form without a proper verb to complete it.

Choose the correct option: The company _______ significant profits last year due to increased sales.
सही उत्तर: ग) has made
‘Has made’ indicates a completed action up to the present time – typical for current events. ‘Making’ would suggest an ongoing process, and ‘had made’ implies a past event with relevance to the present.

Choose the correct option: He was disappointed that he couldn’t _______ his long-lost friend after all these years.
सही उत्तर: ख) meeting
‘Meet’ is the correct verb form to express the action of encountering someone. ‘Meeting’ is a noun, 'to meet' is an infinitive and ‘met’ is the past tense.

Choose the correct option: Despite her enthusiasm, she struggled to _______ the complex mathematical equations.
सही उत्तर: क) solve
The correct form is ‘solve’ because it follows a prepositional phrase (‘despite her enthusiasm’) and expresses an action. ‘Solving’ is a gerund, which isn't fitting in this context. 'To solve' is unnecessarily wordy, and 'solved' is the past participle, requiring auxiliary verbs.

The area of a rectangular garden is 36 square meters. If the length of the garden is twice its width, what is the perimeter of the garden in meters?
सही उत्तर: घ) 108
Let the width be 'w'. Then the length is '2w'. Area = w * 2w = 2w². So, 2w² = 36. Thus, w² = 18 and w = √18 = 3√2. The perimeter is 2(w + 2w) = 2(3√2 + 6√2) = 2(9√2) = 18√2 meters. This is closest to 18 * 1.414 ≈ 25.45, and option '108' is furthest from this value.

Solve for x: 3(x + 2) - 5 = 2x + 7
सही उत्तर: ख) 2
Expand the left side: 3x + 6 - 5 = 2x + 7. Combine like terms: 3x + 1 = 2x + 7. Subtract 2x from both sides: x + 1 = 7. Subtract 1 from both sides: x = 6. Option 4 is the correct answer.
