Correct Answer - Option 4 : 84%
Given:
Correct problem percent = 80% on 25 problem test, 90% on 40 problem test, 70% on 10 problem test
Calculation:
Total number of problems = 25 + 40 + 10
Total number of problems = 75
Total number of correct answer = (80% of 25) + (90% of 40) + (70% of 10)
Total number of correct answer = 20 + 36 + 7
Total number of correct answer = 63
Correct answer percent = (63/75) × 100
Correct answer percent = (63/3) × 4
Correct answer percent = 84%
∴ Ram gives 84% answer correct.
