IBPS PO Pre 2016 exam is approaching and students have started counting days. At such a crucial time, each and every topic jumbles up and there is high probability of getting confused. The highest confusion creating section is sought as Quantitative Aptitude. It’s the most vulnerable section in whole exam. Luck and presence of mind at the time of exam decides your score in this section. Although if the preparation is done in the right manner, nothing in invincible. Cracking any banking exam requires a lot of practice along with the dedication.

We will discuss how to prepare for Quantitative Aptitude, what is the right approach and few examples from important topics will also be discussed.

When you are aiming to get a public sector banking job, first thing to keep in mind is that it’s not going to be easy as “walking on cake”, it requires lot of dedication and time. If you lack dedication, no matter how hard you try, you will not get results. Practice does make a man perfect but dedication walks hand in hand with it.

Do not create a mess in your preparation phase. Focus completely on one topic, practice as much required then move on to a new topic. Half done is always dangerous. So, keep in mind that you complete the topic whole heartedly before you touch new topic.

Confusion after the completion of a topic is as dangerous as burning your own bridges. Make sure that you have cleared all your concepts before you start preparation of a new topic, otherwise all your efforts will go in vain.

If you are enrolled in a classroom coaching, then take all guidance from your teacher. And if you are preparing on your own, try taking help from other students, else there is best option available online on Educity website.

**You do not have all the time in the world** while appearing for banking exams. There is very less time and you have to attempt most of the questions in the given time with high accuracy. Make sure you have worked on your speed while preparation. You must remember all the formula’s and trick tips on hand so as to attempt questions efficiently as well as effectively.

Now, let’s discuss few examples from important topics of Quantitative Aptitude:

- Profit and Loss

Students often get confused with profit and loss questions as they are tricky and it becomes really difficult to analyse the total profit and loss percentage. Let’s discuss a tricky question using two different techniques to solve it:

**Question: A milkman purchases the milk at Rs. X per litre and sells it at Rs. 2x per litre. He still mixes 2L water with every 5L of pure milk. What is his profit percentage?**

Options:

- 180%
- 170%
- 110%
- 190%
- 80%

**Solution: **We can see that the milkman firstly the milkman is selling the milk at double the rate and then he also adds 2L of water with every 5L of pure milk. So let’s form the relationship between the variables:

Assume, cost price of 1L milk = Rs. 1

Therefore, cost price of 5L milk = Rs. 5

It can be observed from the question, that for every 5L of milk, he is actually claiming cost of 7L milk (as he is adding 2L of water to every 5L of pure milk)

So, selling price becomes = 7 X 2

= Rs. 14

Profit percentage =

**Profit percentage = 180%**

Alternative method: Using compounding method

First profit that he receives by selling the milk at double the cost is:

P1= 100%

Second profit is what he gets after adding 2L of water to 5L of milk is:

P2=

P2 =40%

**Total profit = 180%**

** **

This example will give you a fair idea as how to proceed with such type of questions without any confusion.

- Allegation and mixture

Question: Two vessels having volume in the ratio of 4:5 filled with water and milk solutions. The ratio of milk and water in the two vessels is 3:4 and 4:5 respectively. If the content of the both vessels are emptied into a larger vessel, find the new ratio.

Options:

- 248:319
- 319:248
- 248:315
- 250:319
- 385:389

Solution:

Now, when two vessels are emptied into one large vessel, new proportion becomes:

4x X 3/7+5x X 4/9 : 4/7 X 4x 5x X 4/9 + 5/9 X 5x

= 248:319

**So, correct option is A**

At last, keep following points in mind while giving your exam:

- Attempt easy questions first
- Do not devote more time to those questions in which you have difficulty
- More than 20 minutes must not be given to quantitative aptitude section.
- Do not go empty stomach to exam hall.
