Answer 2

Step by Step Explanation :-

${ \large{ \frak{ \underline{ \underline{Let's \: understand \: the \: concept}}}}}$

☘Here we are ask to find the total marks of vinod and gunjan where total questions were 30 and 5 marks are awarded for every correct answer and (-3) marks are awarded for every incorrect answer and 0 for questions which are not attempted. Firstly we will find out vinod's mark who has 24 correct answers and need to find answer and gunjan's mark who has attempts all questions and got 5 incorrect answer and need to find correct answers.

${ \large{ \frak{ \underline{ \underline{According \: to \: the \: question : - }}}}}$

Cᴀsᴇ 1 :

Marks obtained for correct answer = 24 × 5 = 120 marks

No.of incorrect answers = 30-24 = 6

Marks obtained for incorrect answer = 6 × -3 = -18

Total marks obtained for vinod's = 120-18

$\: \: \: \: \: \: \: \: \: \: { \green{ \fbox{ \orange{ \underline{ \pink{ ★{102 \: marks}}}}}}} \: \: \: \: \: \: \: \: \: \: \:$

Cᴀsᴇ 2 :

No.of correct answers = 30 - 5 = 25

Marks obtained for correct answer = 25 × 5 = 125

Marks obtained for incorrect answers = 5 × -3 = -15

Total marls obtained for gunjan = 125 - 15

$\: \: \: \: \: \: \: \: \: \: { \green{ \fbox{ \orange{ \underline{ \pink{ ★{ 110 \: marks}}}}}}} \: \: \: \: \: \: \: \: \: \: \:$
