</li></ol> <h2 id="content-id-3481590276-5"><b> Statistics Questions Solution</b></h2><p>The correct answer is<strong> option 3</strong> i.e. <strong>63.</strong></p>

<p>Given,</p>

<p>(i) 25, 25, 25, 25, 25, and 25</p>

<p>(ii) 5, 20, 35, 15, 55, 20, 40 and 50</p>

<p>(iii) 0.81, 0.098, 12.6, 0.19, 4.902, 4 and 1.4</p>

<p>Mean = Sum of number/Total number of numbers</p>

<p>(i) 25, 25, 25, 25, 25, and 25</p>

<p>Sum of numbers = 6(25) = 150</p>

<p>Total number of numbers = 6</p>

<p>Mean = 150/6 = 25 (Note: When all data is same like "x" then mean value of data is also be a x)</p>

<p>Now, (ii) 5, 20, 35, 15, 55, 20, 40 and 50</p>

<p>Sum of numbers = 5 + 20 + 35 + 15 + 55 + 20 + 40 + 50 = 240</p>

<p>Total number of numbers = 8</p>

<p>Mean = 240/8 = 30</p>

<p>Now, (iii) 0.81, 0.098, 12.6, 0.19, 4.902, 4, 40 and 1.4</p>

<p>Sum of numbers</p>

<p> ⇒ (0.81 + 0.19) + (0.098 +  4.902) + (12.6 + 1.4) + 4 + 40</p>

<p> ⇒ (1) + (5) + (14) + 4 + 40 = 64</p>

<p>Total number of numbers = 8</p>

<p>Mean = 64/8 = 8</p>

<p>The sum of means of (i), (ii), and (iii) = 25 + 30 + 8 = 63</p>
