Question 2: Peter and Paul are two friends. The sum of their ages is 35 years. Peter is twice as old as Paul was when Peter was as old as Paul is now. What is the present age of Peter? Luckily, I had this question twice. Initially I left it because of the confusing statement but when I got the same question second time with different names of the friends (Pooja and Prasad) then I gave a little extra time and solved it. Answer: 20 years. I simply substituted the answers in the statement to find the best fit, because the statement in the question was pretty confusing.

Question 4: (There was a long story, I'll cut short it). There are 5 materials to make a perfume: Lilac, Balsalmic, Lemon, Woody and Mimosaic. To make a perfume that is in demand the following conditions are to be followed: Lilac and Balsalmic go together. Woody and Mimosaic go together,

Woody and Balsalmic never go together. Lemon can be added with any material. (Actually they had also mentioned how much amount of one can be added with how much quantity of the other; but that's not needed for the question.) All of the following combinations are possible to make a perfume except: Balsalmic and Lilac Woody and Lemon Mimosaic and Woody Mimosaic and Lilac Answer: Mimosaic and Lilac. I have made the question here really easy to understand. But the actual question was in a twisted language and it was difficult to find the answer. It took me some time to get to the answer.

What is the probability that same musical sound would be produced 5 times consecutively? ( 1 of _____) ? Answer: 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/32 32 will be the answer. (My friends got similar question with "3 times consecutively"; for that the answer would be 8)

Question 2: Peter and Paul are two friends. The sum of their ages is 35 years. Peter is twice as old as Paul was when Peter was as old as Paul is now. What is the present age of Peter? Luckily, I had this question twice. Initially I left it because of the confusing statement but when I got the same question second time with different names of the friends (Pooja and Prasad) then I gave a little extra time and solved it. Answer: 20 years. I simply substituted the answers in the statement to find the best fit, because the statement in the question was pretty confusing.

Question 3: The ages of two friends is in the ratio 6:5. The sum of their ages is 66.After how many years will the ages be in the ratio 8:7? Answer: 12 years.

Question 4: (There was a long story, I'll cut short it). There are 5 materials to make a perfume: Lilac, Balsalmic, Lemon, Woody and Mimosaic. To make a perfume that is in demand

the following conditions are to be followed: Lilac and Balsalmic go together. Woody and Mimosaic go together, Woody and Balsalmic never go together. Lemon can be added with any material. (Actually they had also mentioned how much amount of one can be added with how much quantity of the other; but that's not needed for the question.) All of the following combinations are possible to make a perfume EXCEPT: 1) Balsalmic and Lilac 2) Woody and Lemon 3) Mimosaic and Woody 4) Mimosaic and Lilac Answer: Mimosaic and Lilac. I have made the question here really easy to understand. But the actual question was in a twisted language and it was difficult to find the answer. It took me some time to get to the answer.

Solution: Here the question appear as an easy one, but carried a lot of unwanted sentences and unwanted datas(i dint mention above) in exam which may confuse u on solving technique. Let x be current average age of first 6 persons in queue and current age of seventh person be y. Then 6x will become the sum of those 6 persons age. Now, let compute the sum of those 6 persons after two years, 6x+12 (as each and individual increase their age by 2). hence its average become (6x+12)/6 = 43 (give in question itself). So now we can compute x from above equation. (x = 41, 6x = 246) Let now we compute y, ((6x+y)/7) = 45, as we have value of x, compute y. Ans: 69 2) Horse started to chase dog as it relieved stable two hrs ago.

After traveling 6 hrs, 2hrs after sunset it got dog. compute the speed of dog? Ans: As we have speed and travel time of horse, we can get distance travelled by it... Hence d = 22*6 = 132km, Exactly this 132km was travelled by dog in 8 hours (as it started two hours earlier). Hence speed of dog = 132/8 = 16.5km/hr Ans:16.5km/hr. 3) 3, 22 , 7, 45, 15, ? , 31 Solution: Here it appear simple, because it arranged in arranged in sequence manner, but the actual question was some what twist mentioning fibonacci series and more over question was in statements (no numbers).. hence first try to understand the question well. here let group alternate terms 3,7,15,31 (3+4 =7, 7+8 =15, 15+16=31) Similarly for second group (22,45,? (22+23 = 45, 45+46 = 91) hence ans is 91. 4) In Tnagar many buildings were under residential category.for buildings they number as 1 to

100. For shops, corporation numbered between 150 and 200 only prime numbers. how many time 6 will appear in building numbering?

...A business undertaking is an organisation which is engaged in some industrial or commercial activity. It represents an institutional arrangement for carrying on any kind of business activity. It may be owned and controlled by a single individual or by a group of individuals who have entered into a formal or informal agreement to jointly conduct the business. Every business undertaking is a separate and distinct business unit. It has its own identity and separate ownership. It can be distinguished from other undertakings on the basis of its ownership, management and control. According to Wheeler, a business undertaking is a concern, company or enterprise which buys and sells, is owned by one person or a group of persons and is managed under a specific set of operating policies".

...The Business Enterprise 1.) Discuss the common elements described in the theories/philosophies of Case, Kouzes, and Drucker including how their principles/strategies relate to the new definition of entrepreneurial leadership presented in Understanding Entrepreneurial Leadership in today’s Dynamic Markets. Case, Kouzes and Drucker each have good theories and philosophies on entrepreneurship and leadership. Each had different ways of stating what they thought made a good entrepreneur but for the most part focus on some of the same things and agreed that with the right balance of these characteristics then succeeding, as an entrepreneur would be possible. One of the common elements that each focused on was people. Interaction with people is important when it comes to entrepreneurship and leadership skills according to Case, Kouzes, and Drucker. Each inferred that if a person does not have people skills, then the person would not succeed as an entrepreneur or a leader. People skills would be the ability to motivate others and interact. A leader cannot lead without being able to interact with people. Starting a business requires interaction with people on some level. Another common element that they all thought were important was not being afraid to take risk. Taking a risk in order to monopolize an industry to succeed is important. The definition of entrepreneurial leadership is one of an enterprising, transformational leader who operates in a......

...The United States exists in a capitalistic economy meaning that private enterprise is based on fair competition, economic freedom, and private ownership therefore; business is the heartbeat of our economy. Everything from manufacturing, health care, sales, and agriculture involves business in some way. Businesses provide jobs and produce goods and services that we depend on every day (What Role Does Business Play in Our Economy..?). They pay state and federal taxes to the government on their services provided. The taxes paid by businesses and the people employed by them allow the government to function. Looking at businesses in this way you can clearly see that business is a pivotal part of the economy. Within our economy two types of business organizations exist: for-profit and nonprofit. A for-profit organization will produce goods or services in the hopes of making revenue off its products. Most organizations you think of today are probably a for-profit establishment. Organizations that are classified as not-for-profit or nonprofit often operate under the guise of the emotional appeal of compassion but can also become major economic engines. They are business like establishments but unlike a for-profit business, their primary goals do not include making monetary profits. For profit businesses operate to generate revenue under the idea to have more profit than loss at the end of the day. Unlike for- profit businesses, nonprofits are organizations that are......
