for every wrong answer. Give the answer of following questions :
(a) Manpreet attempts all the questions but only 4 of them answers are correct, find her total score.
(b) Kartik attempts 14 questions and only 2 of them answers are wrong, find his total score.​

Answer 1

Answer:

(a) 8 . ( b) 44

Step-by-step explanation:

(a) Manpreet correct answer = 4 × 4 = 16

his incorrect answer = 12 × ( -2) = -24

so, his total score = 16 + (-24) = 8 .

(b) Kartik incorrect answer = 2 × (-2) = - 4 .

his correct answer = 12 × 4 = 48.

so, his total score = 48 + ( -4) = 44.

Answer 2

Answer:

Step-by-step explanation:

a) Marks for correct answer = 4*4 = 16

Marks for wrong answer = (16-4)*(-2) = -24

Total marks = 16-24 = -8.

b) Marks for correct answer = (14-2)*4 = 48

Marks for wrong answer = 2*(-2) = -4

Total marks = 48-4 = 44
