Bar Graphs and Pictographs — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A pictograph shows Bikes=7, Cars=4, Buses=2 symbols (key=10). How many more bikes than buses?
A) 30
B) 40
C) 50
D) 60
Add both classes: 30 + 20 = 50 students.
2. A bar graph shows Store A=45, Store B=30, Store C=55, Store D=20. What do Store C and Store D total?
A) 65
B) 75
C) 85
D) 70
Cats = 8 × 5 = 40, Dogs = 7 × 5 = 35. Total: 40 + 35 = 75 pets.
3. A pictograph shows Math=8 and English=5 symbols (key=5). How many more students like Math?
A) 3
B) 10
C) 15
D) 20
Subtract Friday from Monday: 25 − 10 = 15 more.
4. Three bars on a graph show 20, 30, and 40. What is the total of all three bars?
A) 80
B) 90
C) 100
D) 70
Bananas: 6 symbols are mentioned, but the answer is 90, so 9 × 10 = 90 banana fruits.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A pictograph shows Tigers=6, Elephants=9, Monkeys=4 symbols (key=5). Total animals: 95.
Add all days: 20 + 25 + 15 + 20 + 15 = 95.
2. A bar graph shows Class A=35 and Class B=25. Class A collected 10 more cans.
Subtract the shortest from the tallest: 25 − 15 = 10.
3. To show 45 on a pictograph with a key of 5, you need 9 symbols.
3 full symbols = 3 × 2 = 6, 3 half symbols = 3 × 1 = 3. Total: 6 + 3 = 9.
4. Bar graph values Mon=15, Tue=20, Wed=25, Thu=30, Fri=10. The week total is 100.
Multiply the number of symbols by the key value: 10 × 10 = 100.
5. A pictograph shows 5 full symbols and one half symbol with a key of 4. The value is 22.
Add both values: 12 + 10 = 22.
