Answer:

Correct option is

C

50

Let the number of questions answered correctly by

x

∴ The number of questions answered correctly=90−x

Total Marks obtained=60

Marks obtained for correct answer=22

Marks deducted for wrong answer=−1(90−2)=x−90

∴2x+2−90=60

⇒3x=150

⇒x=

3

150

⇒x=50

Therefore the number of question answered correctly is 50
