Question 13

The following pictograph shows the number of tractors in five different villages.

Observe the pictograph and answer the following questions—

a. Which village has the smallest number of tractors?

b. Which village has the most tractors?

c. How many more tractors does Village C have than Village B?

d. Komal says, "Village D has half the number of tractors as Village E." Is she right?

Solution

Understand the Question

Each tractor symbol in the pictograph represents $1$ tractor.
The tractor count for each village is:
- Village A: $6$
- Village B: $5$
- Village C: $8$
- Village D: $3$
- Village E: $6$
We use these counts to compare quantities, find differences, and verify statements.

a. Which village has the smallest number of tractors?

Step 1 · Identify the Smallest Count

From the pictograph: Diagram 1

Comparing the tractor counts ( $6, 5, 8, 3, 6$ ), the smallest number is $3$ .

Therefore, Village D has the smallest number of tractors.

Answer

a. Village D

b. Which village has the most tractors?

Step 1 · Identify the Largest Count

Comparing the tractor counts ( $6, 5, 8, 3, 6$ ), the largest number is $8$ .

Therefore, Village C has the most tractors.

Answer

b. Village C

c. How many more tractors does Village C have than Village B?

Step 1 · Calculate the Difference

Number of tractors in Village C $= 8$

Number of tractors in Village B $= 5$

8 - 5 = 3

Answer

c. $3\text{ tractors}$

d. Komal says, "Village D has half the number of tractors as Village E." Is she right?

Step 1 · Verify Komal's Statement

Number of tractors in Village D $= 3$

Number of tractors in Village E $= 6$

Half the number of tractors in Village E:

\frac{6}{2} = 3

Since this equals the number of tractors in Village D, Komal is right.

Answer

d. Yes

Common Mistakes

Scale Misinterpretation: Always check the scale/key in the pictograph (here, $1\text{ symbol} = 1\text{ tractor}$ , but other problems may use $1\text{ symbol} = 5\text{ or } 10\text{ items}$ ).
Counting Errors: Skipping or double-counting icons when reading longer rows such as Village C.
