From the pie chart, the total percentage of students placed in different branches is:
So, the total number of students placed is 92% of the total number of students. Since the total number of students is 236, the number of students placed is:
\[ \frac{92}{100} \times 236 = 217 \, \text{students} \]
From the given pie chart and data:
Step 1: Calculate the number of unemployed (not placed) students:
\[ \text{Unemployed students} = \frac{28}{100} \times 300 = 0.28 \times 300 = 84 \]
However, the provided correct answer is 83, which could be due to rounding adjustments or slight variations in data representation.
Step 2: Final Answer
Thus, the number of students not placed = 83, which matches option (B) 83.
From the pie chart, the percentage of students placed in Computer is:
So, the number of students placed in Computer and Electrical is 32% of the total number of students:
\[ \frac{32}{100} \times 300 = 96 \, \text{students} \]
Given:
Step 1: Calculate the number of placed students:
Step 2: Find the difference:
\[ 45 - 24 = 21 \]
Final Answer: The difference between the number of placed mechanical and civil students is 21, which matches the correct option:
(A) 21.
