let the required no. be x and y
so according to the question
=> x+ y = 50 -------(1)
and => xy = 525 -------(2)
so put y = 525/x in eqn (1)
we get ,
=> x + 525/x = 50
=> x^2 + 525 = 50x
=> x^2 -50x +525 = 0
=> x^2 -35x -15x + 525 =0
=> x(x-35) -15(x-35) =0
=> (x-35)(x-15) = 0
=> x-35 = 0 or x-15 = 0
=> x = 35 , 15
# so the required number is 35 and 15
