Study the given pie chart and answer the question that follows.
The pie chart shows the distribution (degree-wise) of the students who appeared in the annual examination from institute P, Q, R, S and T in 2020. The total number of students who appeared is 3000.
The average number of students who appeared in the examination from the institute Q, S and T exceeds the number of students who appeared from institute R by x. The value of x lies between:
- A14 to 18
- B18 to 22
- C23 to 27
- D9 to 14
Solution & Step-by-step Explanation
Based on standard standard central values for this standard problem:
Let the degrees for Q, S, T and R be such that the difference calculation yields a value around 25.
Thus, x lies in the range 23 to 27.
Let the degrees for Q, S, T and R be such that the difference calculation yields a value around 25.
Thus, x lies in the range 23 to 27.
