The expression is:

(9050)/100 + (560+01)/10 - 10(9*9/27 + 20)

First, let's simplify each part of the expression individually:

(90*50)/100 = 4500/100 = 45

(560+01)/10 = 300/10 = 30

10(99/27 + 20) = 10(3 + 20) = 1023 = 230

Now, substitute these back into the original expression:

45 + 30 - 230

Now, simplify by adding and subtracting:

45 + 30 = 75

75 - 230 = -155

Therefore, the final result is -155.
