Answer:

(i) The bar graph shows the marks obtained by a student in an examination in various subjects.

(ii) The student is very good in mathematics.

(iii) The student is poor in Hindi.

(iv) Marks scored in English = 60
      Marks scored in Hindi = 35
      Marks scored in mathematics = 75
      Marks scored in social science = 50
      Marks scored in science = 60

∴ Average marks = 60+35+75+50+605 = 2805=56

Answer:

(i) The bar graph shows the number of members in each of the 85 families.

(ii) 40 families have three members each.

(iii) Number of people living alone = 85 − (5+40+25+15)
                                                        = 85 − 85
                                                        = 0

(iv) The most common family is that with three members.
       Each such family has three members .
