Normally there are 50 questions in quantitative section, out of 50, 20 are easy. In most of the exams cutoff hovers around 23-24. So let's discuss some basic maths tricks to get high scores in quantitative section.

But to learn basics you need to refer some good books. Read my earlier post to learn more about beat books for bank exams preparations.4. Solve, solve and solve
The more questions you solve, higher your accuracy will be. Try to solve more questions of each chapter. Solve question of every type whichever you face.During exam
1. Skip questions
Out of 50 questions you need to score 20+ . There are 5-6 questions of high difficulty level, it's better to skip them then wasting time on them. Finding and skipping long and difficult is a skill, you need to master this. Even in 4-5 questions set of quantitative or receiving asking section, if you are not able to understand the question or clueless about how to solve it, skip it or you will end having very low attempt.2. Play with options
7-8 questions in an exam can be solved just by eliminating the options. Take an example,A man bought 18 oranges for 100 rupees and sold 12 oranges for 100 rupees. Calculated profit percentage.
a) 33.333%
b) 50%
c) 66.666%
d) Can't be determined
It can be easily seen that man saved 50% of what he sold. He saved 6 oranges while he sold 12 oranges. Clearly answer is 50%
3. Estimation
Try to estimate answer. You can 't solve 200 and more questions in 2 hours. This trick can be used in profit and loss, time distance, data interpretation and many more chapters.4. Take 100 as base
Many questions can be solved just by taking 100 as base. Take an exampleWhat is the percentage profit in selling an article in discount of 20% which was earlier sold for 40% profit ?
a) 20%
b) 14%
c) 28%
d) 12%
Solution : Lets take Rs.100 as cost of article. Man was selling the article for Rs140 ( 100 cost + 40 profit ) , now he is selling at a discount of 20% , now 140*20/100 = 28. New selling price = 140-28 = 112
