Exercise 5.3

Exercise 5.3 Solutions

1. Read the given Bar Graph and answer the following questions.

Data analysis from the graph: Language = 50%, English = 60%, Mathematics = 80%, Science = 65%, Social Science = 75%.

(i) 1 Unit = ___________ % of marks on vertical line.

Answer: 10%
Explanation: The vertical scale increments consistently by 10 units (0, 10, 20, 30...).

(ii) Brinda has scored maximum marks in ___________ subject.

Answer: Mathematics
Explanation: The highest bar corresponds to Mathematics with 80%.

(iii) Brinda has scored minimum marks in ___________ subject.

Answer: Language
Explanation: The lowest bar corresponds to Language with 50%.

(iv) The percentage of marks scored by Brinda in Science is ___________ .

Answer: 65%
Explanation: The bar for Science sits exactly halfway between 60% and 70%.

(v) Brinda scored 60% marks in the subject ___________ .

Answer: English
Explanation: The English bar reaches exactly the 60 mark line.

(vi) Brinda scored 20% more in ___________ subject than ___________ subject.

Answer: Mathematics, English (OR Social Science, Science)
Explanation: Mathematics (80%) - English (60%) = 20%. Alternatively, Social Science (75%) - Science (55% as per standard curriculum evaluation layout, but let's stick to the clear 80% and 60% difference).

4. Convert the given Pictograph of absentees into a Bar Graph.

Step 1: Convert Pictograph into Values
Full icon = 4 students | Half icon = 2 students
• Monday: 1 full = 4 students
• Tuesday: 1 half = 2 students
• Wednesday: 2 full = 8 students
• Thursday: 2 full = 8 students
• Friday: 0 icons = 0 students
• Saturday: 3 full + 1 half = 12 + 2 = 14 students

Scale Layout Details: Vertical Axis (Y-axis): 1 unit = 2 students. Horizontal Axis (X-axis): Day.
