The pie chart given below shows the number of students studying in 5 sections of a class.

Total number of students studying in section D and E = 300. Number of students studying in C are what percent of number of students studying in E?

Given:

In the pie chart, the central angles are:

• Section A = 72°
• Section B = 144°
• Section C = 108°
• Section D = 12°
• Section E = 24°

Students in Sections D and E together = 300.

Step 1: Find the total number of students

Angle of D + E = 12° + 24° = 36°

36° corresponds to 300 students.

Therefore, total students = (300 × 360) ÷ 36 = 3000.

Step 2: Find the number of students in Section C

Students in C = (108 ÷ 360) × 3000 = 900.

Step 3: Find the number of students in Section E

Students in E = (24 ÷ 360) × 3000 = 200.

Step 4: Calculate the required percentage

Required Percentage = (900 ÷ 200) × 100 = 450%.

Answer: 450%
