Correct Answer: 74


Solution : Given: The average marks of John in English, Maths, Hindi and Drawing = 50
$\therefore$ The sum of marks in English, Maths, Hindi and Drawing = 50 × 4 = 200
The average marks in Maths, Science, Social Studies and Craft = 70
$\therefore$ The sum of marks in Maths, Science, Social Studies and Craft = 70 × 4 = 280
The average marks in all seven subjects = 58
$\therefore$ The sum of marks in all seven subjects = 58 × 7 = 406
Marks scored in Maths = (200 + 280) – 406 = 74
Hence, the correct answer is 74.
