Correct Answer: 74


Solution : The total marks obtained by John in English, Math, Hindi, and Drawing = (50 × 4) = 200
and total marks obtained by John in Math, Science, Social Studies, and Craft = (70 × 4) = 280
Also, the total marks obtained by John in all seven subjects = (58 × 7) = 406
So marks obtained in math are = (200 + 280) – 406 = 74
Hence, the correct answer is 74.
