Correct Answer - Option 1 : 400
Given:
Marks scored in Accounts = 21%
Marks scored in Economics = 24%
Marks scored in English = 15%
Difference of score in Hindi and English = 36
Calculation:
Let the total score be 100x then
Account = 21%, Economics = 24%, English = 15%
Total = 21x + 24x + 15x
⇒ 60x
Remaining score = 100x – 60x
⇒ 40x
Score in Business Studies = 40x × 40%
⇒ 16x
Score in Hindi = 40x – 16x = 24x
Difference of score in Hindi and English = 24x – 15x
⇒ 9x
Value of 9x = 36
⇒ x = 36/9
⇒ 4
Total number of marks = 100x
⇒ 100 × 4
⇒ 400
∴ Total number of marks in the exam is 400.
