Now I tried classes .pull-right and .float-right to place my radio buttons at the right end. Its not working. Coding and Picture below.
<div class="row ">
<div class="form-group col-lg-6">
<div class="row">
<label class="Bold">Is Valid</label>
<input class="radio-inline float-right" type="radio">Yes
<input class="radio-inline float-right" type="radio" >No
</div>
</div>
<div class="form-group col-lg-6">
<div class="row">
<label class="Bold">Is Checked</label>
<input class="radio-inline float-right" type="radio">Yes
<input class="radio-inline float-right" type="radio" >No
</div>
</div>
</div>

You will need to wrap your radio buttons to a div
