Answer 1

Correct Answer - Option 3 : 16

Given:  the difference between A’s and C’s total marks in the exam

Marks obtained by A in Mathematics = 88

Marks obtained by A in Science = 86

Marks obtained by A in English = 66

Marks obtained by C in Mathematics = 72

Marks obtained by C in Science = 68

Marks obtained by C in English = 84

Calculation:

Total marks obtained by A in all subjects together = marks obtained by A in Mathematics + marks obtained by A in Science + marks obtained by A in English 

⇒ Total marks obtained by A in all subjects together = 88 + 86 + 66

⇒ Total marks obtained by A in all subjects together = 240

Total marks obtained by C in all subjects together = marks obtained by C in Mathematics + marks obtained by C in Science + marks obtained by C in English 

⇒ Total marks obtained by C in all subjects together = 72 + 68 + 84

⇒ Total marks obtained by C in all subjects together = 224

∴ the difference between A’s and C’s total marks in the exam = Total marks obtained by A in all subjects together - Total marks obtained by C in all subjects together

⇒ 240 - 224

⇒ 16

Hence, the difference between A’s and C’s total marks in the exam is 16.
