Question

Mahesh scored 65 marks in Hindi, 72 marks in English, 88 in Physics, 70 in Chemistry and 'x' marks in biology. If the marks in each subject is 100, what is the value of 'x' scored  if he scored 74% in the examination 
1. 78
2. 82
3. 68
4. 75
5. 93

Answer 1

Correct Answer - Option 4 : 75

Total marks of the examination = 100 × 5 = 500

Total Marks scored by Mahesh = (74/100) × 500 = 370

∴ 65 + 72 + 88 + 70 + x = 370

⇒ 295 + x = 370

⇒ x = 75

∴ Marks scored by Mahesh in biology is 75
