Linear inequalities word problems play a major role quantitative aptitude test. There is no competitive exam without the questions from this topic. Even though we have been already taught this topic in our school days, we need to learn some more short cuts which are being used to solve the word problems in the above topic.
The only thing we have to do is, we need to apply the appropriate short cut and solve the problems in a limited time. This limited time will be one minute or less than one minute in most of the competitive exams
Students who are preparing to improve their aptitude skills and those who are preparing for competitive exams must prepare this topic in order to have better score. Because, today there is no competitive exam without questions from the topic "Linear inequalities word problems" Whether a person is going to write placement exam to get placed or a student is going to write a competitive exam in order to get admission in university, he must be prepared to solve linear inequalities word problems.This is the reason for why people must study this topic.
we mentioned in the above paragraph, a person who wants to get placed in a
company must write placement test and a student who wants to get admission in university for higher
studies must write entrance exam. To
meet the above requirements, it is very important to score more marks in the
above mentioned competitive exams. To score more marks, they have to prepare
this topic. Preparing this topic would definitely improve their marks in the
above exams. Preparing this topic is not difficult task. We are just going to
remember the stuff that we have already learned.
Students have to
learn few basic operations in this topic and some additional tricks. Already we
are much clear with the four basic operations which we often use in math. They
are addition, subtraction, multiplication and division. Even though we are much
clear with these four basic operations, we have to be knowing some more stuff
to do the word problems which are being asked from this topic in competitive exams.
The stuff which I have mentioned above are nothing but "less than, less than or equal to, greater than & greater than or equal to"
Short cut is nothing but the easiest way to solve word problems related to linear inequalities. In competitive exams, we will have very limited time to solve each problem. Then only we will be able to attend all the questions. If we do problems in competitive exams in perfect manner with all the steps, it will definitely take much time and we may not able to attend the other questions. So we need some other way in which the problems can be solved in a very short time. The way we need to solve the problem quickly is called as shortcut.
Here, we are going to have some word problems on linear inequalities. You can check your answer online and see step by step solution.
1. An employer recruits experienced (x) and fresh workmen (y) for his firm under the condition that he cannot employ more then 9 people. "x" and "y" can be related by the inequality
2. On the average experienced person does 5 units of work while a fresh one (y) does 3 units of work daily. But the employer has to maintain an output of at least 30 units of work per day. This situation can be expressed as
3. The rules and regulations demand that the employer should employ not more than 5 experienced hands (x) to 1 fresh one (y) and this fact can be expressed as
4. The union however forbids the employer to employ less than 2 experienced persons (x) to each fresh person (y). This situation can be expressed as
