Given:
A bar graph indicating the marks obtained out of 50 in mathematics paper by 100 students.
It is decided to distribute workbooks on mathematics to the students obtaining less than 20 marks, giving one workbook to each of such students. A workbook costs Rs. 5.
To do:
We have to find the sum required to buy the workbooks.
Solution:
Number of students who got less than 20 marks $= 27 + 12$
$= 39$
Cost of 1 work book $=Rs.\ 5$
Therefore,
Total cost of 39 work books $= Rs.\ 39 \times 5$
$= Rs.\ 195$
