Study the following pie-chart and answer the following questions.
Total number of students in a college in various fields = 5000
Distribution of the number of students int various fields:
What is the average number of girls in CS, ECE and EEE fields?
Answer & explanation
Correct answer: option 2
Total students of CS = 15%
12% of 5000 = 750
No. of girls in CS = \(\frac{44}{100}\) × 750 = 330
Total students of ECE= 16%
16% of 5000 = 800
No. of girls in ECE = 72% × 800 = 576
Total students of EEE = 18%
18% of 5000 = 900
No. of girls in EEE = 68% × 900 = 612
Total = 330 + 612 + 576 = 1518
Average → \(\frac{1518}{3}\) = 506
