The table shows the percentage of marks obtained by six students in six subjects. The maximum marks for Kannada is 50. What are the average marks obtained by all students together in Kannada?
Show answer & explanation
Answer: C. 36
The table shows Kannada percentages for each student: A (68%), B (80%), C (90%), D (56%), E (72%), F (66%). Converting to marks out of 50: A=34, B=40, C=45, D=28, E=36, F=33. The average is (34+40+45+28+36+33)/6 = 216/6 = 36 marks.
Step-by-step Derivation:
Step 1: Identify Kannada percentages from the table: A=68%, B=80%, C=90%, D=56%, E=72%, F=66%.
Step 2: Convert percentages to actual marks (max=50):
- A: 68% of 50 = 0.68 × 50 = 34
- B: 80% of 50 = 0.80 × 50 = 40
- C: 90% of 50 = 0.90 × 50 = 45
- D: 56% of 50 = 0.56 × 50 = 28
- E: 72% of 50 = 0.72 × 50 = 36
- F: 66% of 50 = 0.66 × 50 = 33
Step 3: Calculate sum: 34 + 40 + 45 + 28 + 36 + 33 = 216
Step 4: Calculate average: 216 ÷ 6 = 36 marks
