Solution

a. The given bar graph shows marks obtained by a student in different subjects out of 100.

b. Subject in which student is very good, Maths as he scored highest marks, i.e. 82.

c. Average marks = `"Sum of all marks obtained in various subjects"/"Total subjects"`

= `(64 + 75 + 82 + 71 + 49)/5`

= `341/5`

= 68.2%

d. In Hindi and Maths, student got 75 and 82 marks, respectively. Since, the marks equal to 75 or above denote a distinction. Hence, student got distinction in Hindi and Maths.

e. Percentage marks = `"Total marks scored"/"Total marks" xx 100%`

= `341/500 xx 100%`

= 68.2%
