You have to do every count in your mind. Try not to utilize paper. You have to complex calculations divide them into parts and settle it in your mind without paper. That is the means by which toppers do complex estimations during competitive exams. it is totally marvelous to perform maths calculations at split second speed. Some eccentric maths traps can diminish the time and exertion required to tackle complex issues. Turn into a maths wizard by attempting these 5 maths traps that will enable you to ascertain quicker.

1. Multiplication with FIVE (5)
Just multiply the figure by 10 and then divide it by 2.
For example 99×5= 990/2= 495

2. Multiplication with NINTY NINE (99)
Multiply the figure with 100 and then minus the same number from the result.
For example
Multiply 32×99 = 3200 - 32 = 3168

3. TIME AND WORK
For example - A takes 10 days to finish a job. B takes 20 days to finish the same job. In how many days they will complete the job if they work together?
A's efficiency = 100/10 = 10% per day
B's efficiency = 100/20 = 5% per days
A and B can do 15% of the work in a day if they work together. So they can do the whole job in 100/15 = 6.66 days or 6 days and 18 hours.

4. ADD REPETED NUMBERS ( For ex 9999+999+99+9 =?)
If in a series all number contains repeating 7.
To find their sum, we start from the left multiply 7 by 1, 2, 3, 4, 5 & 6.
Look at the example below.
777777 + 77777 + 7777 + 777 + 77 + 7 = ?
= 7 × 1 / 7 × 2 / 7 × 3 / 7 × 4 / 7 × 5 / 7 × 6
Add 1 to the total of each category to get your answer
= 7 / 14/ 21/ 28/ 35/ 42= 864192

5. Multiplication with multiples of 5
Whenever we are multiplying a given number with 5 or multiples of 5,
Replace 5 with a multiple of 10 divided by an integer.
For example to calculate 43x25,
Write it as 43x100/4
where 25 is replaced by 100/4.


Theory of Mathematics Tricks for Competitive Exam Mathematics



Mathematics and enchantment may appear a weird blend, however a large number of the most capable supernatural impacts performed today have a numerical premise.
