Problem from Lilavati



          Here is an ancient problem from Bhaskaracharya’s Lilavati:

          A beautiful maiden, with beaming eyes, asks me which is the number hat, 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?
         Well, it sounds complicated, doesn’t it? No, not if you know how to go about it.

Answer:  28 is the answer.

The method of working out this problem is to reverse the whole process- multiplying 2 by 10, deducting 8. Squaring the result and so on.
