### Topic-Wise Questions & Answers- CLAT 2018 Elementary Mathematics Preparation Tips

#### Average:

You can check the below given illustration:

1. The average weight of ten students is increased by 1.8 kg when one student weighing 53 kg is replaced by a new student. Find the weight of the new student.

If we assume the sum of the weights of the other nine students to be x then the earlier average would have been (x + 53) / 10,

Since the weight of those nine students remains constant, and the new average is 1.8 kg more than the earlier one , we have

New Average – Old average = 1.8

(x+ unknown weight)/ 10 – (x + 53) / 10= 1.8

On solving we get

x+ unknown weight – x – 53 = 18

unknown weight – 53 = 18

unknown weight = 18 + 53

Unknown weight = 71 kgs.

To save time during exams we can use this formula directly

• If the average is increased then

Weight of new comer = weight of the person who left+ total increase in weight

Total increase in weight = number of men * increase in average weight

• If the average is decreased then

Weight of new comer = weight of the person who left – total decrease in weight

The total decrease in weight is = number of men * decrease in average weight

#### Time & Work

• These problems mainly deal with the number of workers and the time in which they can complete a given amount of work. The following principles need to be kept in mind while solving such problems.
• If a person can do a given amount of work in n days, the amount of work he does in 1 day is 1/nth of the total work.
• If the amount of work he does in one day is 1/n, the number of days he will take to complete the total work is n days.The following rules determine how the quantities of time, work and number of men vary with respect to each other.
• If we fix the number of men, the work done is proportional to the time.
• If we fix the work, the time is inversely proportional to the number of men.

More men= fewer days are required.

Less number of men= more days are required.

1. If A can do some work in 9 days and B can do the same work in 6 days, in how many days can both of them do it together?

The work is done by A in 9 days

The amount of work done by A in 1 day = 1/9th of the total work

In the same way, the amount of work done by B in 1 day = 1/6th of the total work

Amount of work done by A and B in one day = A’s one day work + B’s one day work

• 1/9 + 1/6
• 5/18th of the total work
• Therefore, number of days required to complete the job are 18/5 = 3.6 days

#### Time & Speed

The time taken to pass a given object

• A train x metres long, while crossing a point object ( like a man, pole or tree) takes the same time as it would to cross the distance of x metres.
• If the train ( of length x metres) has to cross a platform or bridge of length y metres the time taken will be same as the time taken to cover the distance of ( x+y) metres.

Relative speed

• If two vehicles of speeds u km/hr and v km/hr are moving in the opposite direction, their relative speed is (u+v) km/hr
• If two vehicles of speeds u km/hr and v km/hr are moving in the same direction, their relative speed is (u-v) km/hr, where u>v

The time taken to overtake

• If two trains of length x km and y km are moving in the same direction at speeds of u km/hr and v km/hr, the time taken by the faster train to completely overtake the slower train is (x+y)/(u-v) km/hr where u km/hr is the speed of the faster train.
• If two trains of length x km and y km are moving in the opposite directions at speeds of u km/hr and v km/hr, the time taken by them to completely pass each other is (x+y)/(u+v) km/hr.

#### Percentages

Base 1

So to get started with first lets learn something called the golden percentages something which you need to learn by heart ,

1/1 =100%

1/2 = 50%

1/3 = 33.33%

1/4 = 25%

1/5 = 20%

1/6 = 16.66%

1/7 = 14.2857%

1/8 = 12.5%

1/9 = 11.11%

1/10 = 10%

1/11 = 9.09%

1/12 = 8.33%

1/13 =7.69%

1/14 = 7.148%

1/15 = 6.67%

1/16 = 6.25%

Learn these ratios by heart before you proceed on to solving further sums.

### CLAT 2018 Elementary Mathematics Preparation Tips

As already discussed, the section will deal with Mathematics of class 10 level. One of the most scoring sections in CLAT Exam is Numerical Ability or Elementary Mathematics. So, to score the most out of CLAT 2018 in Elementary Mathematics section we have provided some CLAT 2018 Elementary Mathematics Preparation Tips below:

1. Almost all the topics which are listed above are equally important. One can expect questions from each topic, so it is advised to go through all the topics covered in the CLAT Elementary Section. Candidate with sound preparation will be able to attempt the questions easily and quickly

2. The applicants who are quite thorough with the fundamentals of mathematics will have good scope in this section. So, Work on your fundamentals and concepts. Candidate will not be required to perform elaborated steps, conceptual knowledge will be enough to perform calculations

3. One thing which is important to remember about maths is that it is extended logic. So the first step to solve a maths problem is to apply logic, before formulae. This way you are able to strike out the options

4. You can’t afford to give too much time for solving maths sums during clat. Ideally you should take 12- 15 minutes to solve 20 question. Hence you have to forget using the long winding methods we learn at school and try to solve as much as you can in your head. With minimum steps on paper as possible and never more than 3 steps. So you need to cut down the steps and solve the sums as fast as possible by reading CLAT 2018 Elementary Mathematics Preparation Tips

For Example:

If you are given a sum like 5 apples and 4 pears cost as much as 7 pears and 3 apples , then what is the ratio of cost of 1 apple to 1 pear. The options are 3:1, 3:2 , 2:3, 4:5. Here as we see it takes more no of pears are needed (7) when you reduce the no of apples by 1. Hence the cost of apples is going to be higher than that of pears. So the ratios of 2:3 and 4:5, get crossed out , without even the need to solve the sum.

Next step is what follows the English saying.. look before you leap and think before you tick. For example, if you read a offer that says buy stuff worth 2000 and get stuff worth 1000 free, and then you are asked what is the discount you are given, the first number that will come to your mind is 50% as 1000 is half of 2000 and so thats what the answer is, and this is where you need to slow down, the answer to the question is 33.33% as the discount of 1000 you are getting is on 3000 not 2000 and hence the answer. And the Clat paper is full of such googlies, so it is very important that you watch out for them and follow CLAT 2018 Elementary Mathematics Preparation Tips

5. What you need is 30 min a day dedicated to maths esp. for those who are bad at it. And this should increase to 1 hour once boards are over. You might think that, why to work so hard for it, as it carries only 10% weightage. The reason is that maths is not something you can build in a day it needs constant practice over a period of time and other thing is that it’s something you don’t need to revise, so once you are thorough with, you can be at peace . As then you will be able to solve any sum anytime

6. Apart from all the preparation, take up mock tests as much as you can
