I was reading a book on ancient mathematics problems from Indian mathematicians. Here I wish to share one problem from Bhaskaracharya's famous creation **Lilavati**.

### Problem

A beautiful maiden , with beaming eyes, asks of which is the number that multiplied by 3 , then increased by three-fourths of the product, divided by 7, diminished by one-third of the quotient, multiplied by itself, diminished by 52, the square root found, addition of 8, division by 10 gives the number 2 ?

Ahh.. Isn't it very long sentenced problem? The solution is here:

The method of working out this problem is to reverse the whole process --- Multiplying 2 by 10 (**20**), deducting 8 (**12**), squaring (**144**), adding 52 (**196**), 'multiplied by itself' means that 196 was found by multiplying **14** to itself.

Now, **Let the number be **$ n $ .

**Then applying initial part of the problem on it. $ \dfrac {3n+3n \times \dfrac{3} {4} } {7} - \dfrac {1} {3} \times \dfrac {3n+3n \times \dfrac{3} {4} } {7} = 14 $ **

**14 is what we got in first half of solution.
Now we get:
$ \dfrac {n} {2} = 14 $
Thus the number is **

**28**.
