Answer 2

Answer:

Uma attempted 2 answers incorrectly.

Step-by-step explanation:

Marks

For each correct answer = +3

For each incorrect answer = -2

Let no. of questions attempted incorrectly be y

Marks Scored by Uma = 20

No. of correct answers = 8

Marks for 8 correct answers = 3x8 = 24

So,

Total marks = 24+(-2)y=20

=>24-2y=20

=>2y=24-20

=>2y=4

=>y=4/2

=>y=2

Hence,

Uma attempted 2 answers incorrectly.

HOPE IT HELPS,

PLEASE THANK AND MARK AS BRAINLIEST.
