Question

In a competition, 5 marks are given for every correct answer and (-2) marks are given for every incorrect answer . AAyushi scored 30 marks .lf she got 10 correct answers ,how many questions she answered incorrectly ?​

Answer 1

Answer:

10

Step-by-step explanation:

Marks given for one correct answer = 5

So, marks given for 10 correct answers

= 5 X 10 = 50

Aayushi's 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

hope it helps
