Applying Tint value to RGB color (PowerPoint)

Question

I am parsing PowerPoint file and trying read colors used. Following is small part from parsed ppt file. Here I am trying to get proper RGB color.

<a:solidFill>
    <a:schemeClr val="tx1">
    <a:tint val="75000"/>
</a:schemeClr>

So here original RGB Color is - 45555F(R-36,G-85,B-95) Tint value applied is 75%

Desired color after applying tint has to be - 94999D(R-148,G-153,B-157)

I tried multiple algorithms from following reference links but not getting desired output, Can anyone explain how to apply Tint to RGB and get resultant RGB color values

Given an RGB value, how do I create a tint (or shade)?
