Science	25	35

 

Solution:

Step 1: Calculate the total marks obtained by Mohit and Shikha.

Subject	Shikha’s Marks	Mohit’s Marks	Total marks
English	15	30	45
Hindi	25	35	60
Math	10	40	50
Science	25	35	60

 

Step 2: Follow the given steps to construct subdivided bar diagram.

(i) Draw X and Y axes.

(ii) Mark subjects on X-axis by keeping equal gap between two consecutive subjects.

(iii) By choosing a proper scale, mark marks on Y-axis. Here, we take 1 cm = 10 marks.   

(iv) Draw the bar…
