Number of correct answers ⇝ 65

Number of incorrect answers ⇝ 35

Total marks :

☞ (65 × 3) + (35 × -1)

☞ 195 + (-35)

☞ 195 - 35

☞ 160

Hence, the marks scored by Neha is 160.

Answer 2

Given:

Total number of questions= 100

Marks for each correct answer = 3

Marks for each wrong answer = -1

Number of correct answers = 65

⇒ Total marks for correct answers = 65×3 = 195

Given, Number of wrong answers = 35

⇒ Total marks for wrong answers = 35×-1 = -35

Total marks obtained = Total Marks for correct answers - Total Marks for wrong answers

= 195 - 35

= 195 - 35

= 160

Therefore, total marks obtained by Neha are 160 marks.
