Question

For getting distinctionat least 75%marks are required helen secured 447 marks and missed distinction by 3marks find total marks of the examination

Answer 1

The total marks of the examination in which Helen appeared is 600.

• Let the total marks of the examination be x.

• Given, marks secured by Helen = 447

• Marks by which Helen missed to secure a distinction = 3

• Therefore, marks which Helen required to attain a distinction = 447 + 3 = 450

• According to the question,

75 % of x = 450

Or, ( 75 / 100 ) ×  x = 450

Or, 75x / 100 = 450

Or, x = ( 450 × 100 ) / 75

Or, x = 600

∴The total marks of the examination = 600
