Question 1. The bar chart represents the number of students using different modes of transport. Observe and answer the following questions.
(a) Which mode of transport is mostly used by the students?
(b) How many students come to school by walking?
(c) Which mode of transport is used the least?
(d) How many students come to school by Bus?

(b) 40 students.
(c) Car.
(d) 40 students.
In simple words: Look at the picture of the bar chart. It shows how many students use each type of transport like bicycle, walking, car, and bus. Find the tallest bar for "most used" and the shortest bar for "least used". Then read the numbers for how many students walk or use the bus.

🎯 Exam Tip: When analyzing bar charts, always check the labels on both axes (e.g., "Number of students" and "Modes of transport") and the scale to correctly interpret the data.

Question 2. The following information shows the grades of science and maths of 30 students of class 5.

Answer the following question.
(a) How many students got equal grades in both subjects.
(b) How many students got a higher grade in science than in maths?
(c) Which was the most common grade in science?
Answer:
(a) Two
(b) Eight
(c) C.
In simple words: Look at the table carefully. For part (a), count the number of students who got the same grade in both science and maths. For part (b), count how many students had a better grade in science than in maths. For part (c), see which science grade appears most often.

🎯 Exam Tip: When working with two-way tables, identify the row and column headers correctly. To find 'equal grades', look at the diagonal where science grade equals maths grade.

Question 3. Mr. binesh collected the information about the rainfall of a particular city in a week from the newspaper and recorded his information in the pictograph.
Answer the following question.
(a) On which day, the rain was most?
(b) On which day, the rain was least?

(b) Sunday & Wednesday (6 mm).
(c) 6 mm.
(d) 12 mm.
(e) 74 mm.
In simple words: Look at the rain chart. Each little droplet stands for 2 millimeters of rain. Count the droplets for each day to find how much rain fell. Then you can see which day had the most or least rain, and add them all up for the total.

🎯 Exam Tip: Always pay attention to the key in a pictograph. Each symbol might represent a certain number, so multiply the number of symbols by the value of each symbol to get the correct total.

Question 4. Neela, Mala, Kola and Balo were neighbours. The following dato shows the number of fish in each of their fish tank, brow pictogroph to represent the data and Answer the questions.

Note: \( \supset \) = 4 fishes

(b) Neela.
(c) 8.
(d) 40 fish.
In simple words: This chart uses fish symbols to show how many fish each person has. Each symbol means 4 fish. Count the symbols for each person and multiply by 4 to find their total fish. Then, you can answer the questions by comparing these numbers.

🎯 Exam Tip: Always remember to check the symbol key in a pictograph before calculating. For comparison questions, find the totals for each person first, then subtract to find the difference.
