</li></ol> <h2 id="content-id-2035148976-5"><b> Percentage Questions Solution</b></h2><p>The correct answer is<strong> option 2 </strong>i.e.<strong> 0.47.</strong></p>

<p>Let the total widgets = 100</p>

<p>M1 produces = 60</p>

<p>Defective from M1 = 3% of 60 = 1.8</p>

<p>M2 produces = 40</p>

<p>Defective from M2 = 5% of 40 = 2</p>

<p>Total defective = 1.8 + 2 = 3.8</p>

<p>Probability it came from M1 = <span class="math-tex">\(1.8 \over3.8\)</span> = <span class="math-tex">\(9\over19\)</span> = 0.47</p>
