Question 1 :
If the difference between mean and mode is $63$, the difference between mean and median is?

Question 2 :
The mean and median of same data are 24 and 26 respectively. The value of mode is :<br>

Question 3 :
Observations of a data are $16, 72, 0, 55, 65, 55, 10 $ and $41$ Chaitanya calculated the mode and median without taking the zero into consideration. Did Chaitanya do the right thing?

Question 4 :
In a moderately a symmetrical distribution. The mode and median are $75$ and $60$ respectively, find mean.

Question 5 :
The following table shows ages of 300 patients getting medical treatment in a hospital on a particular day.<br>Find the median age of patients<br><table class="wysiwyg-table"><tbody><tr><td>Age (in years)</td><td>10 - 20</td><td>20 - 30</td><td>30 - 40</td><td>40 - 50</td><td>50 - 60</td><td>60 - 70</td></tr><tr><td>No. of Patients</td><td>60</td><td>42</td><td>55</td><td>70</td><td>53</td><td>20</td></tr></tbody></table>

Question 7 :
The&#160;mode of the following data is $50$. Calculate the value of X.<br/><table class="wysiwyg-table"><tbody><tr><td>Marks</td><td>$50-60$</td><td>$60-70$</td><td>$70-80$</td><td>$80-90$</td></tr><tr><td>Students</td><td>$1$</td><td>$2$</td><td>$x$</td><td>$4$</td></tr></tbody></table>

Question 8 :
If the median of the following frequency distribution is $32.5$, find the missing frequencies.<br/><table class="wysiwyg-table"><tbody><tr><td>Class interval<br/></td><td>Frequency<br/></td></tr><tr><td>0-10<br/></td><td>$f_1$<br/></td></tr><tr><td>10-20<br/></td><td>5<br/></td></tr><tr><td>20-30<br/></td><td>9<br/></td></tr><tr><td>30-40<br/></td><td>12<br/></td></tr><tr><td>40-50<br/></td><td>$f_2$<br/></td></tr><tr><td>50-60<br/></td><td>3<br/></td></tr><tr><td>60-70<br/></td><td>2<br/></td></tr><tr><td>Total<br/></td><td>40<br/></td></tr></tbody></table>

Question 9 :
An incomplete distribution is given below:<br/><table class="wysiwyg-table"><tbody><tr><td>Variable<br/></td><td>Frequency<br/></td></tr><tr><td>$10-20$<br/></td><td>$12$<br/></td></tr><tr><td>$20-30$<br/></td><td>$30$<br/></td></tr><tr><td>$30-40$<br/></td><td>$f_1$<br/></td></tr><tr><td>$40-50$<br/></td><td>$65$<br/></td></tr><tr><td>$50-60$<br/></td><td>$f_2$<br/></td></tr><tr><td>$60-70$<br/></td><td>$25$<br/></td></tr><tr><td>$70-80$<br/></td><td>$18$<br/></td></tr></tbody></table>If median value is $46$ and the total number of items is $230$.<br/>Find the missing frequencies $f_1$ and $f_2$.<br/>
