. In a class test 20 questions were asked, 4 marks are given for each correct

Mosayeed attempted all questions but 9 of them were correct. Zeeshan attempted

15 questions and 10 questions were correct. Rishant attempted 18 questions and

15 were correct. Calculate the score of Mosayeed, Zeeshan and Rishant. Who scored more​

Answer 1

Step-by-step explanation:

M attempted 20 out of 20 correct=9

Z attempted 15 out of 20. correct=10

R attempted 18 out of 20. correct=15

marks=4 for each correct ;(-2) for each incorrect

;0 for not attempt

solution:-

For M

score for correct=9×4=36

score for incorrect=(-2)×11=-22

total of M=36+(-22)=14

For Z

score for correct=10×4=40

score for incorrect=5×(-2)=-10

total score of Z=40+(-10)=30

For R

score for correct= 15×4=60

score for incorrect=3×(-2)=-6

total score of R=60+(-6)=54

so the highest score is of Rishant
