Question

In a class test containing 20 questions, 3 marks are given for every correct answer and 1 mark is deducted (–1 mark is given) for every incorrect answer and zero for not attempt the question. Sheela attempted 15 questions out of which only 9 are correct. The marks scored by Sheela is:

Answer 1

Answer:

27

Step-by-step explanation:

attempted 15 out of which 9 are correct so

1 correct answer = 3 marks

so according to my calculation it is 9 x 3 = 27

there fore sheela has scored 27

Answer 2

Given Data is

Total no. of questions = 20

for correct ans. = 3 marks

for wrong answer= (-1) mark

not attempted=0

Now in the case of Sheela, she attempted 15 questions out of which 9 are correct.

incorrect questions will be 15-9= 6

not attempted questions will be 30-19=11

now let's come to the final calculation

for correct answers, she will get 9*3= 27 marks

for 6 wrong answers, she will get 6*(-1)= -6 marks

for not attempted questions, she will get 11*0=0 marks

total marks of Sheela will be 27-6+0= 19 marks

ALTER.

single-line solution of this question maybe

(correct question* marks for correct question)- (incorrect question* marks for incorrect question)= total marks obtained

(9*3)-(6*1)= 27-6=19
