Question
Pooja collected data on the number of tickets sold at the Bhopal railway station for a few different cities of Madhya Pradesh over a 2-hour period. She used this data and prepared a bar graph on the board to discuss the data with her students, but someone erased a portion of the graph. (i) Write the number of tickets sold for Vidisha above the bar. (ii) Write the number of tickets sold for Jabalpur above the bar. (iii) The bar for Vidisha is 6 unit lengths and the bar for Jabalpur is 5 unit leng
Answer

(i) The number of tickets sold for Vidisha is 24.
(ii) The data shows that 20 tickets were sold for Jabalpur. This number should be written above the corresponding bar on the graph.
Hence, the number of tickets sold for Jabalpur is 20.
(iii) If the bar for Vidisha (which represents 24 tickets) is 6 units long, then each unit represents 4 tickets.
Similarly, for Jabalpur, 20 tickets divided by 5 units, also equals 4 tickets per unit.
Hence, the scale for this graph is 4 tickets per unit length.
(iv) The bar for Sagar should be draw with a height of 4 units because 16 tickets were sold for Sagar and the scale is 4 tickets per unit.
(v) The seals should be labeled on the vertical axis with each unit representing 4 tickets.
The numbers would’be marked as 4, 8, 12,16, 20, 24, 28 and so on.
(vi) Seoni sold 16 tickets, so the bar should be 4 units high which is correct and Indore sold 28 tickets, so the bar should be 7 units high. Therefore, given bar for Indore is not correct.
Correct bar for Indone is given below.
