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 ?

Rather than just saying that 28 works as a solution, how about showing how it was found? Start with 2, then work backwards.
2(10) = 20
20-8 = 12
12² = 144
144+52 = 196
√196 = 14
(3/2)14 = 21
21(7) = 147
(4/7)147 = 84
84/3 = 28
