NIACL AO Quantitative Aptitude Strategy 2021

Tips and Tricks to score high marks in quant section   

NIACL AO Quantitative Aptitude Strategy

Divide your attempt strategy on the basis of category of questions  

Now, don’t divide it as per topic such as profit and loss, percentage, etc. Divide them as per the categories mentioned above which are: speed maths questions, arithmetic, and data interpretation. This way you will be able to devise a clear attempt strategy. Otherwise, if choose to go topic-wise it will become too chaotic.  

Approach Quant section with the mindset of 30+ attempts  

In clerical examinations the entire game is about getting maximum attempts with solid accuracy. And when you have 35 questions; then it is a must you attempt 30+ question. Doing so will help you in maximising your chances of clearing the prelims cut-off.   

Practice Speed Maths Tricks and Methods  

No quant-based exam was ever cleared without the help of speed math tricks. Without them you can solve questions but you will be way behind in keeping up with the speed. You should expect at least 50% of the paper on speed math related problems. Here are some speed math tricks and learning resources.

Divide your time as per the category of questions  

The total time for NIACL AO paper is 60 minutes. Let’s assume you need 19-20 minutes for reasoning section. Then you are left with the same time range for numerical ability section as well. So, you have to solve 30+ questions within 20 minutes.   

 You can divide your time in the following manner:  

15 speed math questions – 6 minutes  

10 DI based questions – 8 minutes  

If 10 Arithmetic questions – 6 minutes (7-8 attempts)  

Even if you leave 2-3 questions from arithmetic it will keep you overall attempt at 30+. 

Avoid pressure to not compromise on attempt and accuracy  

There is no need to take pressure during the exam. You have done your hard work and now is the time to attempt questions which you have practiced, revised, and have attended classes or coaching for. So, let go of the pressure or it will affect your accuracy, speed, and time. You will even take time to solve question which you know by heart, but still, you might crumble.   

DI Topics to cover  

• Tabular graph  
• Line graph  
• Bar graph  
• Pie Chart  
• Mixed DI  

• Case-let DI  
• Missing DI  
• Arithmetic base DI 

Percentage tips & tricks  

• Learn about conversion of fraction into percentage  

• Learn about conversion of percentage into fraction  
• Focus on conceptual building as percentage can help you in solving a lot of quant questions apart from this very topic.   

Simplification Tips and Tricks  

• Learn to make tables by yourself – For example – make the table of 87 using speed math tricks. This way you will not have to mug up the tables.  
• Sum, sub, multiply, divide  

• Square values till 25, Cube values till at least 20, Square roots, Cube root  
• Basic fractions  
• Basic percentage and ratio 

Number Series Tips & Tricks  

A question of number/wrong terms series   

Direction: Find the wrong term in the given series: 800, 678, 579, 497, 434, 385, 349  

1. 494  

2. 385  

3. 800  

4. 579  

5. 349  

Things to learn:  

• Logics – Notice the pattern of the series. If it’s based on addition, subtraction, cubes, square, etc.  
• Sequence to implement these logics – Follow a step-based protocol for recognizing the sequence.  

Step-based protocol for sequences (Missing terms)  

6. Check if the sequence is based on square, cube, square +, sqaure -, cube +, cube –  

7. Check if the sequence is based on Multiplication +-, Division +-  

8. Look for double/triple series is being used  

9. Look for illogical series is given (rarely given)  

Now look for logics as well during these steps. However, for wrong term series you can directly just follow the steps.   

Conclusion 

In any of the competitive exam it is evident that you will have to move ahead with the strategy of maximum attempts along with accuracy. It’s better you divide your time among various category of questions. Solve mini mocks regularly to test your speed and accuracy. That’s the only way to ensure that you finish the exam within the time limit.  

Start with the basics and then move to the advanced level. Focus on conceptual learning first. Implement speed math methods instead of just learning them. Take regular free mocks at your convenience.
