Question

In a test (+5) marks are given for every correct answer and (-2)marks are given for every incorrect answer. Jay also answered all the questions and scored (-12) marks though he got 4 correct answers.How many incorrect questions he attempted ?

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

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
