*there are 100 multiple choice questions in a test. If a candidate gets 4 marks for every correct answer and for every unattempted or wrongly answered questions, two marks are deducted from the total score of correct answers. If a candidate scored 244 marks in the test, how many questions did he answer correctly*
Pls answer with one variable as the question is of linear equations

Answer 1

Answer:

Step-by-step explanation:

maximum marks =400

let the number of correctly attempted questions be 100-x

so, the number of unattempeted or wrong question = x

total marks for correct answers =4(100-x)

total marks for incorrect answers =(x)(2)

                                                       =2x

400-4x-2x=244

156=6x

x=156/6

=26
