In this article we are going to discuss about the shortcut tricks in vedic mathematics that can help us a lot in calculate in competitive examinations.
इस आर्टिकल में हम वैदिक गणित द्वारा किसी भी प्रश्न का हल कम समय में प्राप्त करने की विधि के बारे में जानकारी लेंगे।
1) How to find square of number ending with 5
Let's learn it with an example we have to find the square of 35 then do what you have to do it you have to multiply the number on the left of digit 5 to itself plus one and to put 25 at the end of the obtained result
(35)^2 =3*(3+1)....25at end
= 12..25 = 1225
Now let's try the same method for three digit number the number is 115
115^2 = 11*(11+1)...25at the end
= 11*12...25at end
=13225
Now you have to try does it works for you ?
2) Multiplying any number by 5
Divide the number by 2 that is half that number if the remainder is zero at the end of half but if decimal number is in and then ignore the decimal and put five at the end of the half.
56788×5
Half the number 56788/2 = 28394. Remainder is 0 so put 0 at end of the half
Ans: 283940
137×5
Half the number 137/2 = 68.5
Remainder is in decimal so ignoring decimal points and putting five at the end of answer we have 685.
Now you can try the method for any number you want it works always.
3) Multiplication of any two digits number between 10 to 20
Step 1.First add the unit digit of smaller number to larger number.
Step 2.Now multiply the result by 10
Step 3.Multiply the unit digits of both the number
Now at the result of step 2 and 3 that's the final answer
For example 12 x 17
Step 1 .17 + 2 equal to 19
Step 2 . 19 x 10 equal to 190
Step 3. 2 x 7 = 14
190 + 14 = 204
4) Dividing any number by 5
We just have to follow only 2 steps first multiply the given number by 2 and in second step shift the decimal point
For example 27 divided by 5
27 x 2 = 54
shifting decimal place on the left 5.4.
