A contractor employed some workers to finish construction of a road in...

Let he initially employed x workers which works for D days and he estimated 100 days for the whole work and then he doubled the worker for (100-D) days.
D * x +(100- D) * 2x= 175x
=> D= 25 days
Now , the work done in 25 days = 25x
Total work = 175x
Therefore, work done before increasing the no of workers =

A contractor employed some workers to finish construction of a road in...

Solution:

Given:
- Initially, the work was scheduled to be completed in a certain time.
- Later, the work was delayed by three-fourth of the scheduled time.
- The contractor doubled the number of workers to finish the road on the scheduled time.

Let's assume:
- Let the total work to be completed be represented by 1.
- Let x be the fraction of work completed before increasing the number of workers.
- After increasing the number of workers, the remaining fraction of work to be completed is (1 - x).

Calculation:
- Before increasing the number of workers, the work completed by the initial number of workers is x.
- The work remaining to be completed after increasing the number of workers is (1 - x).

- With double the number of workers, the time taken to complete the remaining work is 1/2 of the time initially required.
- Therefore, the work done by the additional workers is (1 - x)/2.

- The total work completed by all workers is x + (1 - x)/2 = 1.
- Solving the equation, we get x = 2/3.

Conclusion:
- Therefore, 2/3 of the work had been completed before increasing the number of workers to finish the road on the scheduled time.

Similar GMAT Doubts

To maximize profits, an employer should control his or her environment in a factory, shop, or office and make sure that examples of energy and efficiency are numerous enough to catch employee attention and establish an atmosphere of industry. In the workplace, there are instances in which it would be in the mutual interest of the employer and the employees to increase the speed of work, but conditions may limit or forbid the use of pace-setters. In construction work and in some of the industries, where there are minute subdivisions of operations and continuity of processes, this method of increasing efficiency is very commonly applied with the use of time cards and software. In many factories, however, such an effort to speed up production might stir resentment, even among the workers paid at a fixed rate for each unit produced or action performed, and have an effect exactly opposite to that desired. The alternative, of course, is for the employer to secure unconscious pace setting by providing incentives for the naturally ambitious men and women in the way of a premium or bonus system or other reward for above-average efficiency.Accordingly, to take advantage of the benefits of conscious or voluntary imitation, workers must be provided with examples that appeal to them as admirable and inspire the wish to emulate them. A common application of this principle is seen in the choice of department heads, foremen, and other bosses. Invariably these people win promotion by industry, skill, and efficiency greater than that displayed by their direct peers, or by mastery of their skills that enables them to show their less efficient peers how any and all operations should be conducted. This focusing of attention upon individuals worthy of imitation has been carried much farther by various companies. Some create weekly or monthly papers published primarily for circulation within the organization to record every incident reflecting unusual skill, initiative, or personal power in an individual member of the organization. A big order closed, a difficult contract secured, a complex or delicate operation performed in less than the usual time, a new personal record in production, the invention of an unproved method or machinewhatever the achievement, it is described and glorified, its perpetrator praised and held up for emulation. This, indeed, is one of the methods by which the larger sales organizations have obtained remarkable results.Which of the following best illustrates an instance of successful unconscious pace-setting?

"Temporization" is a strategy by which an employer increases the number of employees performing a task while slightly decreasing the aggregate number of hours that employees dedicate to this task. Not only does it speed up the completion of tasks, but it also ensures employee satisfaction. The reason is that the aggregate number of hours dedicated to a task cannot be decreased unless employees feel satisfied in their work.The claim made above regarding productivity rests on a questionable presupposition that ____.

Comparable worth, as a standard applied to eliminate inequities in pay, insists that the values of certain tasks performed in dissimilar jobs can be compared. In the last decade, this approach has become a critical social policy issue, as large numbers of private-sector firms and industries as well as federal, state, and local governmental entities have adopted comparable worth policies or begun to consider doing so.This widespread institutional awareness of comparable worth indicates increased public awareness that pay inequities—that is, situations in which pay is not "fair" because it does not reflect the true value of a job—exist in the labor market. However, the question still remains: have the gains already made in pay equity under comparable worth principles been of a precedent-setting nature or are they mostly transitory, a function of concessions made by employers to mislead female employees into believing that they have made long-term pay equity gains?Comparable worth pay adjustments are indeed precedent-setting. Because of the principles driving them, other mandates that can be applied to reduce or eliminate unjustified pay gaps between male and female workers have not remedied perceived pay inequities satisfactorily for the litigants in cases in which men and women hold different jobs. But whenever comparable worth principles are applied to pay schedules, perceived unjustified pay differences are eliminated. In this sense then, comparable worth is more comprehensive than other mandates, such as the Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964. Neither compares tasks in dissimilar jobs (that is, jobs across occupational categories) in an effort to determine whether or not what is necessary to perform these tasks—know-how, problem-solving, and accountability—can be quantified in terms of its dollar value to the employer. Comparable worth, on the other hand, takes as its premise that certain tasks in dissimilar jobs may require a similar amount of training, effort, and skill; may carry similar responsibility; may be carried on in an environment having a similar impact upon the worker; and may have a similar dollar value to the employer.It can be inferred from the passage that application of "other mandates" (see highlighted text) would be unlikely to result in an outcome satisfactory to the female employees in which of the following situations?I. Males employed as long-distance truck drivers for a furniture company make $3.50 more per hour than do females with comparable job experience employed in the same capacity.II. Women working in the office of a cement company contend that their jobs are as demanding and valuable as those of the men working in the cement factory, but the women are paid much less per hour.III. A law firm employs both male and female paralegals with the same educational and career backgrounds, but the starting salary for male paralegals is $5,000 more than for female paralegals.

To remain financially sound, health insurance companies must charge higher rates to insure people considered a higher risk. Lacking complete information about individuals, insurers are forced to set a standard rate, based on the average risk of the group, for a particular segment of the population. Consumers in poor health are willing to pay for the insurance, knowing that it will cover their higher-than-average health-care costs. In contrast, healthy consumers often decide to forgo the insurance, reasoning that it is less expensive to pay out-of-pocket for their lower-than-average health-care costs. The result, called “adverse selection,” is that the riskier members of a group will comprise the group of insurance applicants, potentially leading to a market failure in which insurance companies cannot afford to offer insurance at any price.Among people over age sixty-five, even the wealthy can have difficulty obtaining fairly priced medical insurance, simply because of their age. However, those who blame so-called insurance company greed and discrimination against the elderly are ignoring the reality of adverse selection. Younger people generally obtain health insurance through their employers’ group insurance plan.Employer’s plans obligate all employees to enroll in the plan and effectively pre-screen for general health, as a minimum health level is required to hold a job. Insurance companies can therefore charge a lower premium, based on the lower average risk of the employee pool, without worrying that healthy employees will opt out of the plan.Consumers over sixty-five, typically not employed and thus seeking insurance individually, are necessarily more vulnerable to market failure stemming from adverse selection.Q.The passage states which of the following about the cost of health-care?
