Question

In a test (+5) marks are given for every correct answer and (-2) marks are given
for every incorrect answer. Neha answered all the questions and scored 30
marks though she got 10 correct answers. How many incorrect answers did
she attempt?​

Answer 1

Answer:

She answered 10 questions incorrectly.

Answer 2

Marks given for one correct answer = 5

So, marks given for 10 correct answers

= 5 X 10 = 50

neha score = 30

Marks obtained for incorrect answer

= 30- 50 = -20

Marks given for one incorrect answer

= (-2)

Therefore, number of incorrect answers

= (−20)÷(−2)=10

Step-by-step explanation:

hope this answer is correct.
