Let's solve the problem step by step using the
double line graph provided in the image.
---
Understanding the Graph
- The graph shows the
total strength of students from
Grade 1 to Grade 5.
- There are two lines:
-
Red line = Girls
-
Green line = Boys
- The y-axis represents the
number of students (from 0 to 90).
- The x-axis represents the
grades (Grade 1 to Grade 5).
We will now answer each question based on the data from the graph.
---
Question 1: What is the strength of boys in Grade 4?
- Look at the
green line (boys) at
Grade 4.
- The point for boys in Grade 4 is at
20 on the y-axis.
✔ Answer: 20

Question 2: Which Grade has the same number of boys and girls?
We need to find a grade where the
red line (girls) and
green line (boys) intersect or have the same value.
Check each grade:
-
Grade 1:
- Boys ≈ 20, Girls ≈ 15 → Not equal
-
Grade 2:
- Boys ≈ 50, Girls ≈ 60 → Not equal
-
Grade 3:
- Boys ≈ 40, Girls ≈ 40 →
Equal!
-
Grade 4:
- Boys ≈ 20, Girls ≈ 70 → Not equal
-
Grade 5:
- Boys ≈ 60, Girls ≈ 80 → Not equal
✔ Answer: Grade 3

Question 3: What is the total number of girls and boys in Grade 5?
-
Girls in Grade 5 (red line): ≈
80
-
Boys in Grade 5 (green line): ≈
60
- Total = 80 + 60 =
140
✔ Answer: 140

Question 4: What is the strength of girls in Grade 2?
- Look at the
red line (girls) at
Grade 2.
- The point is at
60 on the y-axis.
✔ Answer: 60

✔ Final Answers:
1)
20
2)
Grade 3
3)
140
4)
60
