A line graph shows runs in 4 matches: 50, 80, 60, 90. By what percent did runs in the 4th match exceed the average of all 4?
A20%
B25%
C28.57%
D33.33%
Answer & Solution
Correct answer: C. 28.57%
1. Average = (50 + 80 + 60 + 90) / 4 = 70.
2. 4th match exceeds avg by 90 − 70 = 20.
3. % = 20 / 70 × 100 ≈ 28.57%.
