Question

Find Ekadhikena Purvena of the number 37.
A) 38
B) 36
C) 30
D) None of these

Answer 1

Hint: The word ‘ Ekadhikena Purvena’ means ‘ by one more than the previous’.
So, before solving this question, let us look at some examples:-
1) Ekadhikena Purvena of the number 46 = (46+1) = 47.
2) Ekadhikena Purvena of the number 23 = (23+1) = 24.

Complete step-by-step answer:
As mentioned in the hint above and shown in the examples, ‘Ekadhikena Purvena’ means ‘by one more than the previous’.
Therefore, the Ekadhikena Purvena of the number 37 is (37 + 1), i.e. 38.
Hence, the answer of this question is (a) 38.

Note: ‘Ekadhikena Purvena’ is also a method in Vedic Mathematics, used to find squares of numbers ending with a ‘5’, i.e. the unit digit of the number must be ‘5’.
Let us see the steps to find the square of a number ending with 5 using ‘Ekadhikena Purvena’ in Vedic Mathematics:-
1) First of all, we need to check whether the unit digit of the number, whose square we need to find, is 5. Let us take an example. Say 25.
2) Now we will apply ‘Ekadhikena Purvena’ to find the square of the number 25.
3) We will firstly add one to 2 to get 3 and then, we will multiply them, i.e. we will multiply 2 by 3. Multiplying them, we got a 6.
4) Remember that the last two digits of the square of 25, or any other number with unit digit as 5, will always be 25.
5) Now, joining these steps together, we get 625, which is the square of 25.
