Step-by-step explanation:

Let the required number be x.

 \therefore \: 75 + 85 \:  \% \: of \: x  = x \\  \\  \therefore \: 75 + 0.85 x  = x \\  \\ \therefore \: 75  = x - 0.85x \\  \\ \therefore \: 75  = 0.15x \\  \\ \therefore x =  \frac{75}{0.15}  \\  \\ \therefore \: x =  \frac{7500}{15}  \\  \\    \huge\red{ \boxed{\therefore \: x =  500}}
