Question

The table below shows the number of bicycles sold from a shop during 7 weeks:

Week		1		2		3		4		5		6		7
Number of bicycles sold		60		70		80		100		50		20		10

(i) How many bicycles bicycles were sold during the sixth week?

(ii) During how many weeks were at least 40 bicycles sold?

(iii) During which all weeks were more than 50 bicycles sold?

(iv) Draw a line graph showing these details.

Answer 1

(i) The table shows that the frequency of sixth week is 20.

Thus, 20 bicycles were sold during the sixth week.

(ii) The table shows that the frequency of five weeks (1^st, 2^nd, 3^rd, 4^th and 5^th week) is 40 or more than 40.

Thus, during the first 5 weeks, at least 40 bicycles were sold.

(iii) The table shows that the frequency of five weeks, i.e., 1^st, 2^nd, 3^rd and 4^th week is more than 50.

Thus, during the first four weeks, more than 50 bicycles were sold.

(iv) In order to draw the line graph of the given data, we represent the week on the x-axis and number of bicycles sold on the y-axis with the appropriate scale.

Here is the line graph representing the given data.
