• All the students have had their fair share of
  mathematics in school and college, but when it
  comes to solving aptitude questions, they
  struggle. The main reason they struggle is a time
  constraint. A simple math question can be solved
  by everyone, but if you have 50 questions to
  solve in 60 minutes, then your speed should be
  really good. I am not talking about
  your problem-solving speed, I am talking about
  adopting some methods that reduce your
  calculations dramatically and enable you to
  arrive at the answer in a fraction of the time
  you were spending earlier. In other words, you
  need to analyze different ways to solve
  quantitative aptitude questions and use the
  fastest among them

 Use the options given to solve

• In a lot of quantitative aptitude questions, you
  can analyze the options given and easily
  eliminate the ones which cannot be justified with
  the question. Here is an example for you.
• Question Ages of A and B are in the ratio 74,
  after 5 years, the ratio becomes 117. What is
  the age of A?Options A. 11,  B. 18,  C. 21,  D.
  28
• Now, you know the age of A must be a multiple of
  7, and you can quickly eliminate option A and B.
  Now pay attention to option C, if we take the age
  of A as 21, then after 5 years, A will be 26
  years old. However, 26 is not a multiple of 11,
  and according to the question, As age after 5
  years should be amultiple of 11. There you go,
  eliminate option C too. Now youre only left with
  option D which is the answer. 28 is indeed a
  multiple of 7 and after 5years it would become
  33, which happens to be a multiple of 11

 Dont compute everything, use options to
identify

• If you are given a complex calculation to do,
  just think for a second, there has to be a better
  way to do it. Because complex calculations are
  not tested in an aptitude test, your smartness
  is. Below is an example to for more clarity.
• Question 3812  5972 ?Options A. 456284, B.
  658598, C. 765454, D. 501570
• Now, to arrive at your answer, you can either
  manually calculate the squares or you can think
  in a smarter way. Square of 381 will definitely
  have the last digit of 1. (11)2 is 121, (21)2 is
  441, (31)2 is 961, and so on. So, 3812 would be
  something like this xxxxx1. Similarly, square of
  597 would be something like this, xxxxx9. 72 is
  49, and the last digit is 9, so 5972 has to end
  with 9. Now that you have 2 numbers, xxxxx1 and
  xxxxx9, just add them like an old fashioned
  addition question

Use effective percentage

• The concept of effective percentage can help to
  reduce your calculation time dramatically.
• You must have seen poster and banners outside
  shops offering 50 30 discount. The same kind
  of questions can be seen in most aptitude tests

6
Learn basic percentages

• If you want to calculate 10 of something, you
  would cut the zero at the end, or put a decimal.
  This much is known by most people and they dont
  do (number x 10/100). But what to do when you
  want to calculate 25 of a number? Or 76 of a
  number? You must be equipped with basic
  percentagerules to solve these things quickly.
