Puzzles and Curious Problems by Henry Ernest Dudeney: $143$

"Lilivati", A.D. $1150$
Beautiful maiden, with beaming eyes, tell me 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 $2$?

Historical Note

Henry Ernest Dudeney quotes this in its entirety as an example of one of the problems in Lilavati, by Bhaskara $\text {II}$ Acharya, dating from approximately $\text {1150}$ $\text {C.E.}$

In Dudeney's words:

Here is another little morning problem from Lilivati (A.D. $1150$)...
... This, like so many of those old things, is absurdly easy when properly attacked.

It will be noted that he refers to it as Lilivati, which is most probably incorrect.
