Question

What is the basic sutra of Ekadhikena Purvena method?
(a) One more than the previous one.
(b) One less than the previous one.
(c) Two more than the previous one.
(d) Two less than the previous one.

Answer 1

Hint: In order to solve this problem, we need to find out the Sanskrit translation of the word. The basic sutra is to add one to the previous value. We can show that with the help of many examples. The common example is that we can find the square of any number which starts by units place.

Complete step by step answer:
The Ekadhikena Purvena is the Sanskrit sutra and the translation is given by (Increment the previous by 1).
This method of increasing is used often in vedic maths.
We can use it to find the square of complicated numbers.
We can example with the help of an example.
Let’s try to find the value of ${{25}^{2}}$ .
The main condition in this example is we need to check that there must be 5 in the unit’s place.
The trick is we need to square the number 5 directly.
The square of 5 is 25.
The tens place is 2. So now we will use the Ekadhikena Purvena and add 1 to 2.
We get the number 3 and just multiply 2 by 3.
We get 3. Now, we need to place the 6 to the right-hand side of 25.
We get the number 625.
Hence, the square of 25 is 625.
Similarly, we can do this procedure to find the square of any number.
In this way, the Ekadhikena Purvena is used in many ways in vedic mathematics.

So, the correct answer is “Option A”.

Note: In the example, we showed we need to be careful that this rule is applied only whose unit place is 5. The Sanskrit translation of the word pruvena is “previous”. And the translation of the word of Eka-dhikena is “One more”. Therefore, we can get the answer form here as well.
