x+0.19+x+0.20+x+0.21++x+0.91=542\left\lfloor x+0.19 \right\rfloor +\left\lfloor x+0.20 \right\rfloor +\left\lfloor x+0.21 \right\rfloor + \ldots + \left\lfloor x+0.91 \right\rfloor =542

If xx satisfies the equation above, find the value of 100x\left\lfloor 100x \right\rfloor .

Note that X\left\lfloor X \right\rfloor denote the floor function of XX.
